Low heart rate

"Low pulse" - we often hear this verdict from a doctor and do not quite understand what it means, as well as what can cause such a pathological process. In order to find out the nature of a low pulse, you should understand what this medical concept is.

So, the pulse is a rhythmic fluctuation of the blood volume in the vessels, caused by the contraction of the myocardium and determined by the pressure in the vessels during one cardiac cycle. This process manifests itself in the form of beats when palpating large vessels.

In a normal state, the pulse varies from 60 to 80 beats per minute. This indicator is measured in a horizontal position and preferably in the morning. It should be noted that the pulse rate can be affected by such a factor as a person's age. For example, in newborns, the pulse is usually 140 beats / min., and in elderly people - only 65 beats / min. The highest pulse is in children under 7 years old, most often it is equal to 100 beats / min. With age, the pulse decreases, and in old age its indicator becomes the lowest. However, doctors have found that before death, the pulse can increase again and sometimes reach 160 beats / min.

The pulse has the ability to change depending on the physical and emotional state of a person. For example, when running and doing other physical activities, it increases; stress, fear, fright and other emotional states can also cause an increase in the pulse rate.

Causes of low pulse

A low pulse is an abnormality associated with a decrease in heart rate.

The causes of low pulse are very diverse. These include arterial hypertension, pain syndromes, malnutrition and improper use of medications. Various changes in the work of the heart very often cause bradycardia. In addition, the pulse can decrease due to a person being in cold water for a long time, severe stress, intense physical activity. If a low pulse is diagnosed, it is necessary to consult a cardiologist for an examination. It should be noted that the heart rate depends on the blood pressure: accordingly, the lower the blood pressure, the lower the pulse will be. If a person has hypotension, causing bradycardia, it is necessary to start taking medications that stimulate blood pressure. Among the causes of low pulse, one can also note oxygen starvation associated with a sedentary lifestyle and lack of active activity. Deviations in the work of the heart can be observed in people of different ages, which is associated with heredity, our constitution, as well as the number of acquired diseases.

The cause of pathological bradycardia lies in organic heart disease and myocardial dysfunction, i.e. the presence of ischemic heart disease, coronary atherosclerosis, myocarditis, or post-infarction cardiosclerosis. In addition, the causes of decreased heart rate can be endocrine and nervous diseases, increased intracranial pressure, severe intoxication and various infections.

[ 5 ]

Why is the pulse low?

A low pulse is a signal of a heart rhythm disorder. However, true bradycardia can only be considered if the pulse and heart rate are the same according to the ECG data.

Many people are interested in the question: "Why is the pulse low?" Among the reasons for this phenomenon, physiological conditions and various organic pathologies can be noted. There are often cases when a person naturally has a low pulse, but there are no organic changes in the heart.

A decrease in pulse rate can be caused by pathological disorders in the nervous and endocrine systems, thyroid gland function, VSD, as well as cardiovascular diseases: myocarditis, atherosclerosis, ischemia, etc.

A low pulse rate may be an indicator of an infection in the body, as well as signal increased intracranial pressure and other disorders in the functioning of the brain (meningitis, oxygen starvation of the brain, etc.). Taking certain medications, in particular beta-blockers, can also lead to a decrease in pulse rate.

The presence of several types of bradycardia requires a thorough examination of the patient with a low pulse to determine the main cause of this condition. Physiological bradycardia does not require treatment as such. But if the examination results prove that the patient has pathological bradycardia, which is associated with problems in the conduction system of the heart, the underlying pathology should be treated. Only then will the person's pulse be restored.

What is considered a low heart rate?

Low pulse rate is a very common occurrence and is caused by an irregular heart rhythm.

What pulse rate is considered low? In medicine, it is generally accepted that when the pulse rate is below 55 beats/min. there are all grounds for diagnosing a person with pathological processes associated with a malfunction of the heart. This disorder is also called "bradycardia". Usually, a decrease in pulse rate to 50 beats/min. is observed with low blood pressure. In addition, this indicator depends on physiological reasons: for example, the pulse rate tends to decrease at rest or during deep sleep (most often in athletes). This process is also observed when a person stays in a cold room for a long time, or when there is a sharp change in climatic conditions. If the pulse rate decreases for no known reason, it is necessary to be examined by a doctor.

A decrease in the pulse rate to 50-40 beats/min., first of all, signals about failures in the work of the heart muscle, therefore, when observing such a symptom, a person needs to consult a cardiologist for further medical examination. First of all, an electrocardiogram should be done. If the results of the examination show that the pulse is equal to the heart rate, i.e. the indicators of these two concepts are equal, then there is every reason to believe that the patient is developing bradycardia.

What does a low pulse rate indicate?

A low pulse rate signals heart rhythm disturbances due to myocardial dysfunction. There may be several reasons, one of the most common is low blood pressure.

What does a low pulse indicate? First of all, it indicates the development of cardiac pathology, especially if bradycardia is confirmed by the results of an electrocardiogram. Such pathology develops due to dysfunction of the sinus node of the heart (the main driver of the heart rhythm), which produces electrical impulses. The consequence of this process may be insufficient supply of organs and tissues with oxygen, as well as substances necessary for their full functioning. This leads to various disorders and failures in the work of internal systems and organs. At first, a low pulse may not bother the patient, but over time, other clinical symptoms of bradycardia join it:

• frequent dizziness and headaches;
• general weakness and fatigue;
• nausea and vomiting;
• fainting.

Changes in pulse can also be caused by endocrine pathologies, psychological stress, various thyroid diseases and taking hormonal drugs. Slow pulse is a companion of such dangerous heart diseases as ischemic heart disease, arterial hypertension, congenital and acquired defects, myocardial infarction.

Lowest heart rate

Low pulse (bradycardia) is a very dangerous condition that causes a lack of oxygen, which primarily affects the human brain. As a result of this pathology, frequent, sudden fainting spells occur, and the person begins to be bothered by dizziness and headaches. In addition, due to a decrease in pulse to the maximum of 40 beats/min. and less, a person may experience severe weakness, chronic fatigue, and general malaise. One of the main symptoms of this condition is also the appearance of cold sweat.

The lowest pulse rate – less than 40 beats/min. – can provoke cardiac arrest, which, naturally, without emergency medical care is fraught with a fatal outcome. That is why, if you have symptoms of bradycardia, you should consult a cardiologist as soon as possible for an accurate diagnosis of heart disease. The primary method for examining the condition of the heart will be an electrocardiogram. Such studies as coronary angiography, ultrasound of the heart, tests with atropine, Holter monitoring (conducting a daily examination of the heart using a portable electrocardiograph) may also be needed. If the medical examination does not reveal any serious heart pathology, the patient needs to consult other doctors – a neurologist, endocrinologist, therapist, etc. in order to find out the true cause of the heart rhythm disorder.

Bradycardia often bothers athletes and physically active people. In this case, the symptom has no clinical significance. Often, a pulse rate of 60-40 beats/min. is associated with a person's constitution, is transmitted genetically, and is also found in people with unstable functioning of the autonomic nervous system (pronounced lability), who have a predominance of the vagus nerve tone.

It should be noted that people experience bradycardia differently. Some experience symptoms such as frequent dizziness and general fatigue with a heart rate of 45-50 beats/min, while others feel practically nothing with a heart rate of 37-40 beats/min. Despite this, a low pulse cannot be called normal, because in this state the body does not receive enough oxygen, and along with it, various nutrients necessary for the normal functioning of all internal organs and systems.

Symptoms of low pulse

A low pulse rate may be asymptomatic, especially if it is a physiological feature of a particular person. In this case, there is no reason to worry - this symptom does not threaten health.

Symptoms of a low pulse, which is caused by problems with the heart or other organs, can manifest as dizziness, headaches, fainting, which is most often caused by oxygen starvation. A person may also experience weakness, chest pain, shortness of breath, fatigue, absent-mindedness and memory loss. If such symptoms occur suddenly and for no known reason, there is reason to believe that bradycardia is present - a heart rhythm disorder characterized by a low heart rate and pulse rate (less than 60 beats/min.).

Potential complications of bradycardia include frequent fainting, heart failure, and in severe cases, even sudden cardiac arrest. Therefore, it is so important to promptly pay attention to the symptoms of such a pathological condition and consult a doctor. Low pulse may not necessarily be caused by heart disease; common causes of this symptom include endocrine pathologies, low blood pressure, intoxication, diseases of the nervous system, infectious diseases, and increased intracranial pressure.

Weakness and low pulse

A low pulse rate may be accompanied by symptoms such as dizziness, nausea, weakness – this is often due to low blood pressure.

Weakness and low pulse can be signs of cardiovascular and other diseases. It is important to remember that a decrease in pulse to 40 beats/min. is dangerous to health, since this condition causes a lack of oxygen in the brain. In turn, this manifests itself in dizziness and weakness, as well as chronic fatigue and fainting states.

Muscle weakness in the limbs with a low pulse may indicate hyperthyroidism - increased function of the thyroid gland. Additional symptoms in the development of this pathology may be nervous excitability, insomnia, weight loss with a good appetite, trembling fingers, etc. General weakness against the background of a low pulse is caused by intoxication of the body in infectious diseases, as well as poisoning and the use of certain medications.

Slowly increasing weakness and decreased pulse rate often occur with heart disease. In this case, patients note constant weakness and fatigue, especially with increased physical activity and even after it. In addition, other symptoms are observed: shortness of breath, chest pain, swelling of the extremities. Weakness is often combined with drowsiness, sweating, absent-mindedness, headaches, irritability. Such a complex of symptoms may signal the development of arterial hypotension (low blood pressure). It should be noted that with such a pathology, even sleep does not bring the long-awaited vigor - on the contrary, in the morning hours, weakness with low blood pressure is especially pronounced. To make an accurate diagnosis, if weakness, low blood pressure and other unpleasant symptoms are observed, you should consult a doctor.

Arrhythmia and low pulse

A low pulse can throw a person off track, especially if it is accompanied by a number of other symptoms: chest pain, shortness of breath, cold sweat, fainting. This is often associated with arrhythmia - a pulse disorder characterized by uneven intervals, heart stopping, interruptions in its work. It is quite easy to detect arrhythmia - by manually measuring the pulse, or by digital blood pressure monitors, which are also equipped with a pulse meter and arrhythmia detector.

Arrhythmia and low pulse – what do these symptoms indicate? First of all, about the possible development of heart disease. It should be noted that in most cases, arrhythmia is secondary to the underlying disease, i.e. this symptom is caused by some pathology, a malfunction of the heart muscle, which can only be detected by a medical examination.

Arrhythmia due to the development of bradycardia is dangerous because low blood circulation has a negative effect on all internal organs of a person. In addition to the disturbance of heart contractions, a person experiences weakness, dizziness, and may lose consciousness. For example, hypertension, thyroid dysfunction, heart failure, low potassium levels in the blood, and congenital heart disease can cause the so-called " atrial fibrillation ", which is characterized by chaotic contraction of the atria. This pathology leads to extremely ineffective ejection of blood and disruption of the entire blood circulation. In turn, poor blood circulation can provoke shortness of breath, rapid fatigue, and cause heart pain. Only treatment of the underlying disease can help get rid of arrhythmia against the background of a low pulse.

Low pulse in the morning

A low pulse rate is not necessarily an indicator of any disease or pathological process in the body; in the morning hours it is the norm, which is caused by the slowdown of all processes in the body during the period of relaxation and rest.

A low pulse in the morning may be less than 60 beats/min., but this indicator fluctuates throughout the day. Usually, the pulse slows down by late evening, too, ‒ this is caused by physiological processes and does not indicate a health problem if a person is not bothered by other symptoms. It should be taken into account that in a lying position, the pulse will also be lower than in a standing or sitting position. Thus, to track the process of changing the pulse, it is recommended to measure it at the same time and only in a horizontal position. In this case, the most accurate values will be when counting the pulse for 1 minute.

If a person, in addition to a low pulse, is bothered in the morning by headaches, severe weakness, shortness of breath, dizziness and other unpleasant symptoms, this indicates the possible presence of vegetative-vascular dystonia of the hypotonic type, or hypofunction of the adrenal cortex or thyroid gland. In a pathological condition, a low pulse in combination with low blood pressure in the morning is observed in hypotensive patients, people who have experienced a traumatic brain injury, and also those suffering from various chronic diseases. In any case, to determine the cause of poor health, it is necessary to undergo a medical examination.

Low pulse after heart attack

A low pulse after a heart attack is a common occurrence. If the patient feels well, this indicator should not particularly worry him.

However, often after a heart attack, a low pulse of 55 beats/min. and below indicates the development of bradycardia and hypotension (if the systolic pressure is less than 100 mm Hg). In this case, a medical consultation is necessary. It is dangerous to take any measures on your own, because we are talking about the rehabilitation period of the patient after a heart attack. Medications for normalizing the pulse should be prescribed exclusively by a cardiologist after an examination.

The rapid development of bradycardia indicates poor blood circulation, so it requires an immediate call to an ambulance. In this case, it is necessary to prevent the risk of death. Usually, doctors use intravenous administration of adrenostimulants.

Cardiological rehabilitation after a heart attack is aimed, first of all, at reducing the risk of a repeated attack. One of the main areas of such rehabilitation is constant monitoring of blood pressure and pulse, as well as cholesterol and glucose levels in the blood. In addition, you should follow a diet to normalize cardiac activity, work on losing weight if you are overweight, avoid nervous tension and stress, and take care of physical rehabilitation (initially, in a hospital, strictly under the supervision of a doctor). With moderate physical activity, the pulse should increase, but its value should be carefully monitored. In medicine, a formula is used to calculate the optimal pulse rate: from 220, you need to “minus” the patient's age and multiply the figure by 0.70. An important condition for this is that the patient feels well.

[ 9 ], [ 10 ], [ 11 ], [ 12 ]

Low temperature and low pulse

Low pulse rate, accompanied by a decrease in body temperature below 36°C and other symptoms (apathy, lethargy, general malaise), indicates pathological processes in the body. Among them, it is necessary to highlight a decrease in hemoglobin levels, thyroid dysfunction, adrenal gland damage, fatigue, exacerbation of chronic diseases, lack of vitamin C, decreased immunity during pregnancy, etc. There are many reasons, so it is important to take into account the overall clinical picture, the patient's well-being, the presence of additional signs, chronic diseases in the anamnesis.

Low temperature and low pulse can be combined with tremors, drowsiness, problems with coordination. Most often, these are symptoms of anemia, diabetes, kidney or liver disease, hypoglycemia, parasitic infections, hypothyroidism, pneumonia, etc.

This condition, when blood pressure and pulse decrease, can also be caused by:

• hypothermia as a result of prolonged exposure to cold;
• immersion in cold water;
• wearing clothes out of season;
• excessive use of antipyretic drugs;
• drug addiction and alcoholism.

Of course, if your body temperature is low, accompanied by a decrease in pulse and other symptoms, you should see a doctor in a timely manner. Only a medical examination will help identify the underlying cause of the illness.

Headache and low pulse

Low pulse in combination with low blood pressure (hypotension) can cause headache, weakness, general malaise. Usually the headache is dull, constant, and against its background, pulsating pain of a paroxysmal nature can also occur. Most often, such attacks occur after nervous or mental overstrain. Symptoms of an attack are pale skin and a rare pulse, which can be hardly felt on the forearm.

If you have a headache and a low pulse, you need to see a doctor for an examination. Often, in the case of hypotension, a neurologist's consultation is needed, since this ailment most often overcomes very sensitive, emotional people with a low threshold of stress resistance and a predisposition to depression. Thus, hypotension is the result of stress and psycho-emotional tension of a person.

If the headache and decreased pulse are caused by decreased blood pressure, caffeine-containing products (askofen, citramon, coffee, strong tea) can be used to relieve the pain. Bed rest should be followed for a while. It is recommended to sleep without a pillow, with the head low and legs slightly raised (using a pillow or bolster).

A catastrophic lack of physical activity is one of the main causes of hypotension. So people suffering from this disease should change their lifestyle and move more. Hypotension can be provoked by chronic fatigue, climate change, prolonged bed rest, insomnia, past infections and flu. All of these are temporary conditions that can be corrected.

Dizziness and low pulse

A low pulse is dangerous when accompanied by other symptoms, such as weakness, cold sweat, dizziness, headache, nausea. A slow pulse is associated with a disruption in the heart contraction process. This is the cause of a number of disturbing symptoms.

Dizziness and low pulse indicate impaired blood circulation, this may be a signal of the development of bradycardia - the result of a violation of the electrical activity of the heart, a failure in the transmission of signals regulating the rhythm of cardiac activity. If you ignore such pathologies and allow bradycardia to become neglected, in severe cases a person may experience cardiac arrest.

Slowing of the pulse and occurrence of dizziness may be signs of hypothyroidism, which suppresses the work of the heart muscle, hypothermia, malnutrition, hypothermia, severe exhaustion, as well as VSD, hypotension, anemia. Taking some medications can cause a decrease in the pulse and, as a consequence, dizziness. These can be beta-blockers, digitalis preparations, sedatives and tranquilizers.

In any case, if unpleasant symptoms occur, you should contact a medical center to diagnose the exact cause of the decrease in pulse and accompanying symptoms. Only a medical examination can help in choosing the right treatment.

[ 13 ], [ 14 ], [ 15 ], [ 16 ]

Low blood pressure and low pulse

A low pulse rate accompanied by low blood pressure is a sign of bradycardia. In this case, the heart rate can be only 50 to 30 beats per minute. Naturally, this condition is an anomaly and requires a medical examination to identify the main causes.

Low blood pressure and low pulse rate during the development of bradycardia may occur due to:

• sudden hypothermia of the body;
• pathological changes in the heart muscle (heart defects, myocarditis, angina);
• overdoses of certain medications;
• infectious diseases;
• exhaustion of the human body due to acute lack of nutrients and starvation;
• blows and injuries to the neck or chest;
• severe poisoning with nicotine or heavy metals.

Such conditions may be accompanied by dizziness, severe fatigue, and severe weakness due to insufficient oxygen and blood supply to the body's tissues. The brain is the most sensitive in this regard. Therefore, with prolonged bradycardia, a person often experiences fainting. In this case, it is important to identify the real causes of this condition - heart disease or internal organs, the result of poisoning, etc.

Hypodynamia (blood pressure below 95/60 for women and 100/60 for men) combined with a low pulse rate can be a consequence of a sedentary lifestyle, insomnia, work in difficult conditions (underground, at high temperatures, and also contact with harmful chemicals).

The development of hypotension may be associated with thyroid disease, adrenal dysfunction, problems with the nervous or cardiovascular system, as well as anemia, cholecystitis, peptic ulcer, hepatitis C, etc. Usually, treatment of the disease that caused the decrease in pressure leads to its normalization and restoration of the pulse.

Low pulse with normal pressure

Low pulse can be observed with normal blood pressure. In this case, if a person does not feel any additional symptoms, there is no reason to worry. Often, a decrease in pulse can occur in athletes, active trained people who normally tolerate a condition when the heart rate is below normal with acceptable blood pressure values. However, if, along with a low pulse of 55-30 beats / min., weakness, dizziness, nausea, difficulty breathing, decreased concentration, impaired thinking and other symptoms are observed, there is a reason to worry. In this way, some disease may manifest itself.

What can cause a low pulse with normal blood pressure? First of all, bradycardia, a type of cardiac arrhythmia that in most cases develops as a result of disturbances in the conduction system due to irreversible organic changes in the myocardium (heart defects of various etiologies, hypertension, myocarditis, coronary heart disease). Bradycardia can also be caused by increased activity of the parasympathetic system (for example, when a person bathes in too cold water, etc.). An overdose of beta-blockers, quinidine, cardiac glycosides can provoke a decrease in pulse.

It should be taken into account that bradycardia, which has developed even against the background of normal blood pressure readings, can lead to complications such as shock or arrhythmic collapse - dangerous conditions that often end in cardiac arrest and death. That is why it is so important to promptly determine the cause of bradycardia and begin an effective fight against it. Complex therapy should be carried out under the strict supervision of a cardiologist.

Low pulse with high blood pressure

Low pulse is often a symptom that accompanies various diseases. For example, many hypertensive patients complain of a low pulse. This causes a problem, since taking antihypertensive drugs provokes an even greater decrease in heart rate, and taking medications to normalize the pulse contributes to even greater fluctuations in blood pressure. By the way, blood pressure that exceeds 140/90 is considered high.

What causes this condition? The main causes of high blood pressure against the background of a slow pulse can be:

• weakness of the sinus node;
• endocarditis;
• myocardial defects and blockades;
• various heart pathologies;
• thyroid disease;
• vegetative dystonia;
• side effects of some medications.

Bradycardia often occurs in hypertensive patients during the period of adaptation of their body to temperature changes, or due to overwork, heavy mental stress, chronic fatigue. In such situations, a low pulse is not dangerous, such a symptom is a temporary phenomenon and quickly passes.

What should you do if you have a low pulse with high blood pressure? Naturally, it is best to consult a cardiologist, especially if the decrease in pulse with hypertension has occurred suddenly or is repeated frequently. The patient will need a thorough examination using blood pressure monitoring, an electrocardiogram, a Holter heart study, bicycle ergometry and echocardiography, as well as a study of the functioning of the thyroid gland (in particular, determining the level of hormones and an ultrasound of this organ).

If a patient develops a hypertensive crisis with a low pulse, it is necessary to call an ambulance immediately. While waiting for doctors, the patient should take a horizontal position. You can put a warm compress on the collar zone, or apply a mustard plaster to the legs. It should be noted that self-administration of any medications is unacceptable. This is especially true for drugs that are most often used in the treatment of hypertension, such as Adelfan, Anaprilin, Concor, Verapamil, as well as their analogues.

It should be emphasized that the treatment of hypertension in combination with a tendency to a slow pulse is characterized by its own peculiarities, because in this case not all hypotensive drugs can be used. Usually, the doctor prescribes angiotensin receptor blockers, ACE inhibitors or alpha-adrenergic blockers, as well as diuretics to the patient. It is important to choose the most effective treatment regimen, and only an experienced doctor can do this.

With high blood pressure and low pulse, one should use so-called "alternative" methods of stimulating heart contractions with caution, for example, physical exercise and drinking caffeinated beverages. Even homeopathic drugs should be prescribed exclusively by the attending physician in order to avoid side effects in the form of increased blood pressure while normalizing the pulse.

Very low pulse

A low pulse is a pathology if it reaches extreme limits and is accompanied by a number of symptoms indicating various disturbances in the functioning of the heart or the development of diseases of other internal organs (thyroid gland, liver or kidneys, brain, etc.).

A very low pulse rate of less than 55 beats/min is a cause for concern. In this case, it is customary to talk about the so-called "sinus bradycardia", which, according to most doctors, is considered a borderline state between normal and pathological. Bradycardia is dangerous, first of all, because it can provoke arrhythmia, and in a more severe course - the development of a heart attack and stroke.

Slow pulse can be caused by physical inactivity, decreased metabolism, loss of tone, and excess weight gain. Bradycardia often occurs with a clear sensation of heartbeats, and the pulse gradually decreases. Bradycardia is usually diagnosed by measuring the heart rate and strength. When it reaches a low limit - 55 beats/min. and below, bradycardia becomes very dangerous, because a decrease in pulse and a simultaneous increase in cardiac amplitude are, in fact, a condition of heart failure, which requires immediate medical intervention, since the body cannot cope on its own. The load on the heart increases, while the size of the vessels and the heart grows, reaching values at which their strength is not enough, and this is fraught with rupture. In late forms of bradycardia, pulse rates reach 35-30 beats and below, which threatens cardiac arrest and death.

Pulse below 60

A low pulse of 60 beats/min. is not always a pathological disorder, since the heart rate depends on the level of training and strength of the heart muscle, as well as the normal functioning of the nervous system. It may sound strange, but sometimes a pulse of 40 beats/min. is normal - for athletes who have a well-trained heart muscle. For an ordinary person, a decrease in pulse beyond 60 beats is a deviation from the norm and signals problems with the heart.

What exactly can a pulse rate below 60 indicate? First of all, arterial hypotension, insufficient blood supply to the myocardium and oxygen content in the blood, as well as a deficiency of potassium, magnesium, and calcium in the body. A decrease in pulse can be caused by certain medications, excessive consumption of caffeinated beverages and alcohol. A constant pulse rate below 60 beats/min. may indicate thyroid dysfunction (it is weak), especially if a person feels generally unwell, weak, and also experiences hair loss, constipation, and thermoregulation disorders.

The rate of contraction of the heart muscle is affected by the conduction system, which consists of special muscle fibers that conduct impulses to different areas of the heart. If these pathways are interrupted by diseases or altered by medications, heart block may occur. In this case, the danger increases, since heart contractions can slow down to the level of a heart attack, shock, or infarction.

Pulse below 50

Low pulse is often a factor in the development of pathological processes in the body, especially when its indicator is less than 50 beats. In addition, if a person experiences accompanying symptoms in the form of weakness, headache, difficulty breathing, etc., there is reason to believe that a heart disease or internal organs are developing.

What does it mean when the pulse is below 50 beats/min.? This condition is called "bradycardia" and may indicate the presence of some disease in the body, and in itself it can provoke the occurrence of unpleasant clinical signs - severe fatigue, apathy, headaches. Therefore, if you observe a decrease in pulse rate, you should seek medical advice, undergo an ECG and a number of additional cardiological studies to determine the main cause of the development of this condition.

Severe bradycardia often accompanies heart failure, which is dangerous to human health and can provoke a heart attack or stroke. Pathological causes of bradycardia may include: poisoning of the body with heavy metals, sclerotic changes in the heart muscle, hypothyroidism, increased intracranial pressure, jaundice, prolonged starvation, and other factors.

It should be taken into account that a low pulse rate, the indicator of which is 50 beats/min. and less, is often found in well-trained people and many athletes and is not an abnormality. For example, the pulse of the famous cyclist Miguel Indurain at rest was only 28 beats/min.! At the same time, if the athlete does not feel discomfort and other symptoms, such as rapid heartbeat, dizziness, difficulty breathing, shortness of breath, then his health is normal.

In cases of significant sinus rhythm disturbances, fainting is especially dangerous, since in such cases the risk of sudden cardiac arrest increases. Thus, a severe form of bradycardia requires medical care, in particular, if the patient's life is at risk, it is recommended to install a pacemaker.

Pulse below 40

A low pulse rate, which is only 40 beats/min. or lower, is a factor indicating a strong degree of development of pathological bradycardia. Frequent symptoms of this condition include heart pain, sharp fluctuations in blood pressure, cold sweat, weakness, dizziness and sudden attacks of loss of consciousness.

Why does a pulse rate below 40 lead to such pronounced symptoms? It's all about the lack of blood supply and oxygen starvation of organs and tissues. In such situations, it is necessary to undergo a thorough examination by a cardiologist in order to determine the cause of bradycardia and prescribe medications to effectively combat this pathology.

A sudden attack of bradycardia against the background of prior wakefulness and good health is especially dangerous - this condition is called "conduction block" and can signal a heart attack or even a heart attack, so it requires immediate medical intervention. If the pulse drops to 30 beats/min. or less, this condition can lead to fainting against the background of a decrease in the minute volume of the heart. The person will need an urgent call to an ambulance for resuscitation measures.

Constantly low pulse

Low pulse in combination with low blood pressure is a hypotonic condition, which, if ongoing, threatens insufficient blood supply to the brain and internal organs, leading to disruptions in their functioning. However, if the pulse decreases against the background of normal pressure, the question arises about the causes of such a process.

A constantly low pulse rate of less than 60 beats/min indicates the development of bradycardia, which can be caused by stress, neuroses, gastrointestinal pathologies, endocrine diseases, sleep disorders, increased potassium levels in the blood, and many other reasons. This condition can be both physiological (for example, in athletes, people with a hereditary predisposition to low pulse rate), and pathological (with VSD, hypothyroidism, chronic diseases, in the post-traumatic period or after surgery). If the pulse remains consistently low, this is a reason to see a doctor for an examination, since bradycardia is accompanied by a lot of unpleasant sensations: lethargy, apathy, deterioration of memory and thought processes, rapid fatigue. In addition, this dangerous condition, due to its duration, negatively affects the functioning of all organs and systems and, ultimately, can lead to the development of ischemia, heart attack, stroke in a person.

[ 17 ], [ 18 ], [ 19 ]

Low heart rate

A low pulse is dangerous because the organs, and first of all the human brain, do not receive enough oxygen and important nutrients necessary for normal functioning. Thus, there is a failure in the work of internal organs and systems.

A low heart rate of 55 beats/min. and below is already a pathology indicating the development of bradycardia. Among the factors that provoke a slow heart rate are blood loss, dehydration, vomiting, malnutrition and overdose of certain medications. A weak pulse is often a companion of low blood pressure. This phenomenon should not be ignored, since a violation of blood volume and blood flow leads to an imbalance in the functioning of organs and systems. Symptoms accompanying a low heart rate include increased sweating, frequent dizziness, shortness of breath, rapid fatigue, and fainting.

A weak pulse may indicate a severe degree of heart failure caused by an infection or some internal damage. In such cases, the heart muscle is unable to pump a sufficient amount of blood normally. Blood circulation in the body is disrupted, as a result of which some of the blood returns back to the heart and lungs. This condition leads to a slow pulse. As a result, the patient begins to poorly tolerate the simplest physical activity, and he has chronic circulatory failure that does not respond to conservative treatment methods.

If the heart rate slows significantly, it is recommended to immediately consult a doctor, since in severe cases bradycardia can lead to cardiac arrest, development of ischemia, heart attack or stroke. If arrhythmia recurs, and the person is bothered by other unpleasant sensations (difficulty breathing, chest pain, shortness of breath, loss of consciousness), a visit to the doctor should be immediate.

Low pulse during pregnancy

Low pulse during pregnancy is a very common phenomenon. Usually women tolerate it normally, but there are cases when a decrease in pulse causes unpleasant sensations in the form of dizziness, weakness, fatigue and drowsiness, and in some situations fainting may occur.

A low pulse during pregnancy can be a companion of low blood pressure. If the expectant mother has only a slightly slow pulse, which is at least 55-50 beats/min., this condition does not pose any threat to the health of the child. To bring the heart rate back to normal, the pregnant woman just needs to lie down, relax and have a good rest.

You should be alert in situations where the following symptoms are observed against the background of a decrease in pulse:

• shortness of breath;
• frequent dizziness;
• severe weakness;
• general malaise;
• headaches;
• loss of consciousness.

In such situations, a woman should contact her doctor for additional examination and clarification of the causes that cause such unpleasant conditions. The expectant mother should constantly monitor her blood pressure and pulse and, in addition, regularly visit her gynecologist to monitor the course of pregnancy.

A low pulse in children indicates poor blood supply to the body. It should be noted that the normal pulse rate varies in children of different ages. Thus, at birth, the highest rate is noted - 140-160 beats / min., then a gradual decrease in pulse is observed. Thus, by the age of one year, the child reaches 120-125 beats / min., by two years - 110-115 beats / min. Up to the age of 7, the pulse rate gradually drops to 90 beats / min.

For children aged 8 to 12 years, the norm is a pulse of 80 beats/min., and after 12 years, the norm is a pulse of 70 beats/min., like in adults. A child's pulse rate is measured to assess the condition of his heart and blood vessels. A low pulse in a child often indicates the occurrence of various pathological processes in the body.

Causes of bradycardia in children are:

• diseases of the nervous and endocrine systems,
• increased tone of the vagus nerve as a result of pathological processes in the myocardium,
• infectious diseases,
• hypothermia,
• hypothyroidism,
• severe intoxication,
• problems with cerebral circulation, etc.

If you notice a low pulse rate, your child needs to be examined. It is better to do this without delaying a visit to the doctor, as soon as possible, in order to prevent possible negative health consequences in time.

Low pulse in a teenager

Low pulse in adolescence is most often associated with the intensive development and growth of all internal organs of the child, including the heart. This is the reason for the decrease in heart rate. In addition, the development of bradycardia can occur due to metabolic disorders, as well as due to adolescent neurosis.

A low pulse rate in a teenager is very often accompanied by the following symptoms:

• pain in the chest;
• severe dizziness;
• loss of concentration;
• constant lethargy and weakness;
• rapid fatigue, including against the background of minor physical exertion;
• blood pressure fluctuations;
• difficulty breathing and shortness of breath;
• poor appetite.

In case of exacerbation of the disease, loss of consciousness may be observed as a result of impaired blood circulation in the brain. Bradycardia in adolescents is most often of a short-term nature and is relatively easily corrected by daily routine, diet, optimal combination of sleep and wakefulness phases. Of course, if the child complains of headaches and poor health, an examination should be conducted, and if the diagnosis of "bradycardia" is confirmed, then regularly see a cardiologist.

The conduction system of the heart in an adolescent lags behind the myocardium in terms of development due to the uneven growth of the left and right sections of the heart. The consequence of this process is functional disorders of the contractile function of the heart muscle. Sinus arrhythmia, splitting of tones, extrasystole, palpitations, shortness of breath, and decreased pulse may be observed. A sedentary lifestyle leads to attacks of dizziness, fainting, pain in the chest and abdomen. Adolescents may also experience rapid mood swings, increased sweating, and red dermographism. This occurs due to instability of the endocrine, nervous, and vegetative systems, which is typical for adolescence.

Low heart rate in athletes

Low pulse rate in trained people who actively engage in sports is not uncommon. Physiological bradycardia, reaching 50-40 beats/min., and sometimes even lower values, does not pose any threat. Naturally, if there are no other symptoms, in particular, such as dizziness, difficulty breathing, fainting, loss of strength, severe weakness, discomfort and pain in the chest. Very often, the pulse rate of people who engage in sports decreases at night, in a state of complete rest, and is explained by the fact that during a full night's sleep, the body's need for oxygen decreases.

Low pulse in athletes is usually associated with the development and increased functionality of their cardiovascular and respiratory systems, which provide the brain and other vital organs with oxygen in sufficient quantities even against the background of a rare heart rate. Physiological bradycardia is absolutely not dangerous to human health, since it does not provoke a decrease in the level of blood supply to the brain and other organs. This type of bradycardia does not require special treatment. In the event of any unpleasant symptoms indicating pathological processes, it is necessary to consult a doctor.

Low Heart Rate Running

Running at a low pulse, i.e. at a moderate pace, without intense loads, allows you to achieve positive results in improving the health of the entire body. Such running contributes to:

• strengthening the cardiovascular system;
• increasing the elasticity of blood vessels;
• strengthening muscles and joints; 
• stimulation of full functionality of the respiratory organs;
• oxygen saturation of internal organs;
• improving overall tone.

It is recommended to start a health run very slowly, practically from walking, gradually bringing the pulse to the desired level. In general, its indicator should not exceed 120 beats/min. This is the optimal level for running at a low pulse. The process of healing the body occurs due to the coordinated work of the body without additional loads, such as those observed during intensive running, when glycogen is spent, as a result of which the products of anaerobic decay, in particular, lactic acid in the muscles, cause discomfort when running.

A low pulse during a health run is a prerequisite for achieving positive results. It is necessary to finish such a run with walking, a slow 2-minute walk.

Why is a low pulse rate dangerous?

Low pulse (bradycardia) most often occurs due to disturbances in the heart rhythm due to low blood pressure, digestive system pathologies, frequent neuroses, endocrine diseases. Such a symptom can be provoked by excess potassium in the blood, as well as an overdose of drugs, in particular beta-blockers - drugs that lower blood pressure and heart muscle activity.

What is the danger of a low pulse? First of all, because such a pathology causes insufficient blood supply to the brain and internal organs, which can lead to serious disruptions in their work. This process is especially dangerous for older people, whose blood vessels already poorly maintain tone.

If an attack of bradycardia occurs suddenly, you should immediately call an ambulance. This condition is also called "conduction block," and it can cause fatal arrhythmia. A decrease in pulse to 30 beats/min. can lead to loss of consciousness. In this case, resuscitation measures (inhalation of strong odors, raising the legs, artificial respiration) are desirable even before the ambulance arrives.

The "sick sinus" syndrome (a condition in which the pacemaker of the heart rhythm cannot cope with its work, and the frequency of its impulses decreases) is a fairly common pathological phenomenon in our time. Such a diagnosis can only be identified by the Holter ECG scanning method (daily monitoring of the heart).

What to do if your heart rate is low?

A low pulse, which indicates pathological processes occurring in the body, should not be ignored. In this case, it is necessary to undergo a thorough medical examination in order to identify the main causes of bradycardia.

What to do with a low pulse? First of all, you should do an electrocardiogram, and if necessary, conduct other cardiological studies. If the decrease in pulse is caused by hypodynamia, you should take medications that help increase blood pressure, as well as caffeine-containing tonic drinks with the addition of ginseng or guarana.

An innovative method used in modern medicine to correct the pulse is electrocardiostimulation, which comes down to the use of a special sensor in treatment (the so-called "artificial cardiac pacemaker"). Such a sensor is inserted subcutaneously, and the operation is absolutely painless for the patient and harmless to his health.

A low pulse rate in the case of endocrine system dysfunction requires special attention. Associated symptoms of such a pathological process are constant chills, severe hair loss and brittle nails. Quite often, this condition occurs in workaholics and has another name - "chronic fatigue syndrome". It is provoked by constant fatigue, psychophysical stress on the body, as a result of which it does not have time to properly rest and gradually accumulates negative energy. This negatively affects the functioning of the cardiovascular system.

Low pulse rate against the background of high blood pressure is most often a sign of heart disease, so it requires a special approach to treatment. Especially if the diagnosis reveals hypertension, heart disease, or ischemic disease.

It is necessary to take into account that the human body reacts sharply to sudden changes in temperature, as well as climate change, which may result in a decrease in pulse during the process of adaptation of the body to new conditions. Thus, a decreased pulse may be the result of a person staying in cold water for a long time. In this case, active warming is indicated.

What to do if your pulse is below 50?

A low pulse with a heart rate below 50 beats per minute is considered a symptom of a disease that has the medical name "sick sinus syndrome." The main feature of this disease is a slow heart rate, which is observed at rest, as well as an insufficient increase in this indicator during physical exertion.

What to do if the pulse is below 50? In a situation where a person does not observe any unpleasant symptoms (dizziness, chest pain, weakness), bradycardia does not require special treatment. However, if bradycardia is too pronounced, when the pulse rate drops to 30 beats per minute, short-term cessations of heart contractions may occur. This results in dizziness and pre-fainting conditions, as well as loss of consciousness. Cardiac arrest does not occur in this situation, but attacks are dangerous because a person can be seriously injured when falling during fainting. Patients with bradycardia, which is accompanied by loss of consciousness (frequent fainting), need a thorough medical examination. Usually, such an examination is carried out in a hospital setting. If the diagnosis of "sick sinus syndrome" is confirmed, a pacemaker is implanted in the patient.

If the patient has severe bradycardia of a permanent nature, especially during the daytime and with repeated episodes of fainting, additional medical examination is usually not required. The patient is implanted with a pacemaker without preliminary cardiac tests.

Treatment of low pulse

A low pulse rate should be corrected based on the underlying cause of the disease that caused this symptom. This applies exclusively to pathological bradycardia, ‒ physiological bradycardia does not pose a threat to human life, so it does not require special treatment.

Treatment of low pulse rate should take into account many factors, the main one being the elimination of the disease and normalization of heart rate. Usually, the following drugs are used in the treatment of bradycardia:

• Atenolol,
• Alupent,
• Atropine,
• Euphyllin.

Of course, you can't take medications on your own, because these drugs can cause cardiac arrhythmia. An experienced doctor should think over the optimal medication and treatment plan.

In severe cases of bradycardia, a condition in which the pulse rate is 40 beats/min. or less, the patient undergoes implantation of a pacemaker, a special sensor whose task is to increase the heart rate to normal. The process of increasing the heartbeat is carried out by means of electronic impulses sent by the pacemaker. The device is inserted subcutaneously, under the large pectoral muscle. The operation is not particularly difficult and, in fact, painless. Electrodes are installed inside the heart chambers. The pacemaker operating modes are set using a programmer.

How to increase low heart rate?

A low pulse often causes anxiety and worry in a person who encounters such a symptom for the first time.

The first question that arises in such a situation is: "How to increase a low pulse?" First of all, such a problem as heart rate fluctuations requires consultation with a specialized doctor. Only a correct diagnosis with the help of a medical examination will tell you in which direction to follow to eliminate the problem of a low pulse. If the doctor does not reveal a serious pathology, he will give useful advice and recommendations on what to do at home to normalize the pulse.

One of the common ways to do this is to use a mustard plaster. It is usually placed on the area of the body located slightly to the right of the heart for several minutes. Usually, the optimal time for such a procedure is 3 minutes. Do not perform the manipulation too often, this can lead to negative consequences.

Caffeine-containing drinks, as well as ginseng and guarana decoctions, help to normalize the pulse well. With a low pulse against the background of low blood pressure, a possible cause of this condition is thyroid dysfunction. In this case, the help of an endocrinologist is necessary, who, taking into account the results of thyroid ultrasound tests, hormones, etc., will prescribe effective treatment aimed at normalizing the pulse. Thus, increasing the pulse is a matter for a specialist, only a timely consultation with a doctor and his prescriptions will help get rid of the causal pathology and unpleasant symptom.

What to take for low pulse?

Low pulse often causes such unpleasant sensations as dizziness, sudden weakness, confusion. To find out the main cause of the malaise, you need to undergo a medical examination.

Many people are interested in the question: "What to take for a low pulse?" Only a doctor should prescribe medications to normalize the pulse. Their intake and dosage should be strictly observed according to the instructions, since exceeding the dose can provoke a sharp increase in blood pressure.

As for mild discomfort associated with an attack of bradycardia, with a pulse of 55-50 beats/min. you can drink a cup of hot black tea or ground coffee. The natural caffeine contained in them will begin its immediate effect. To enhance the effect of caffeine-containing drinks, you can add a few drops of ginseng, eleutherococcus or belladonna tinctures purchased at a pharmacy (10-15 drops are enough). In case of a severe attack of bradycardia, accompanied by a decrease in pulse to 35 beats/min., it is not recommended to engage in any folk methods of treatment. This is a very dangerous condition that requires medical intervention and a thorough examination in a hospital setting. Therefore, in the event of a severe attack of bradycardia, you must immediately call an ambulance.

Medicines for low pulse

Low pulse rate should be treated only in cases of its obvious clinical manifestations, when a person has pronounced disturbances in the hemodynamic process.

Medicines for a low pulse rate, the rate of which is 40 beats/min., should be prescribed by a doctor taking into account the dynamics of the disease that caused this pathological process. Usually, the following medications are used to increase the pulse:

• Atropine (administered intravenously or subcutaneously every 3 hours);
• Alupent (intravenously - as part of an isotonic sodium chloride solution, or orally - in tablets of 20 mg);
• Isoproterenol (by infusion);
• Isadrin (intravenously – as part of a 5% glucose solution).

In the treatment of bradycardia, which does not have pronounced negative symptoms, belladonna preparations, as well as ginseng and eleutherococcus extracts have proven themselves well (the dosage of the preparations is selected individually, taking into account the patient's condition). If the patient has contraindications to the use of Atropine or Isadrine, he is prescribed Ipratropium bromide or Ephedrine hydrochloride in tablets.

In case of acute bradycardia caused by a sharp disruption of impulse conduction, the patient must be urgently hospitalized. In such a case, inpatient treatment is required, the main task of which will be the elimination of the causes that caused the decrease in heart rate. Bradycardia is often associated with the patient's age and natural aging (usually irreversible processes occur in the body after 55-60 years). If therapy seems ineffective, the method of electrical cardiac stimulation is used. In this case, a special device is implanted subcutaneously into the patient, the action of which is aimed at normalizing the number of heartbeats.

Help with low pulse

A low pulse can manifest itself as an individual feature of the body, or be a symptom of a serious heart disease, such as myocardial infarction. Everything depends on the person's condition, pulse rate, and the course of the bradycardia attack.

Help with a low pulse usually comes down to calling an ambulance, especially if the heart rate is very low. A patient with an attack of bradycardia, accompanied by loss of consciousness, is hospitalized. In the case of diagnosing pathological bradycardia - a condition that poses a serious threat to human health, an artificial sensor - a pacemaker - is implanted in the patient.

If the pulse is slightly lowered, it is necessary to undergo an examination to identify the main cause of this condition. Self-medication is not recommended, especially you cannot take any medications without first consulting a doctor. It is also important to measure your blood pressure and take a blood test to have an idea of the state of the body.

To increase the pulse, sympathomimetics and anticholinergics can be prescribed - drugs that should be taken under strict medical supervision, since they can cause other heart problems, in particular, ventricular tachycardia and fibrillation. Help with a slightly lowered pulse at home comes down to taking tonic drinks containing caffeine, which helps to increase blood pressure and at the same time - an increase in heart rate.

Folk remedies for low pulse

Low pulse can be treated with well-tested folk remedies if its causes are established and the doctor has allowed the use of such remedies.

So, folk remedies for low pulse:

• Radish and honey. Radish juice with honey helps speed up the heartbeat. You need to cut off the top of the radish and make a small indentation, cutting off a little of the pulp. Then you need to put honey in it and leave it in a glass overnight. In the morning, the resulting syrup should be divided into three doses and consumed throughout the day.
• Lemon and garlic. They are considered the most effective means of combating bradycardia. To prepare a healing remedy, you need to use 10 lemons, squeeze the juice out of them and add chopped garlic (10 heads). Add 1 liter of honey to the resulting mixture, let it brew, take 4 teaspoons on an empty stomach, slowly dissolving the portion for a minute.
• Walnuts. To prepare the recipe, use 0.5 kg of peeled kernels, add sesame oil and sugar (1 cup each). Separately pour 1 liter of boiling water over 4 lemons, cut into 4 parts, mix all the ingredients. Take the finished mixture half an hour before meals three times a day, 1 tablespoon.
• Motherwort. Motherwort juice should be taken by dissolving 30-40 drops in 1 tbsp. of water. It is very effective for weak pulse, cardiac neurosis, shortness of breath.
• Pine shoots. To prepare an alcohol tincture from young pine shoots, you need 70 branches and 300 ml of vodka. Infuse in the sun for 10 days, then take the finished product 20 drops at a time.
• Rose hips. Boil 10 large rose hips in 0.5 liters of water for 15 minutes. Cool the broth, rub the berries through a sieve and mix with 3 teaspoons of honey. Take the finished product daily, half a glass before meals.

To increase the pulse, use a regular mustard plaster. It should be placed in the chest area, closer to the right side. The burning will act as a stimulator of blood flow and, accordingly, increase the number of heart contractions.

Caffeine-containing drinks (coffee, strong tea) are good for low pulse, but can raise blood pressure. Therefore, if low pulse is accompanied by high blood pressure, caffeine intake is contraindicated. Tonic drinks based on eleutherococcus, guarana or ginseng have an effect similar to that of caffeine.

Corvalol for low pulse

Low pulse can be caused by nervous disorders, stress and dysfunctions of the body's autonomic system. In such cases, a person may experience irritability, insomnia, and cardiovascular disorders.

Corvalol for low pulse can help only if bradycardia is caused by nervous disorders, cardiac neurosis, high blood pressure. Usually this drug is prescribed for tachycardia. The drug contains valerian root, peppermint oil and phenobarbital (sleeping pill). The medicine has a calming (sedative) and vasodilatory effect, normalizes blood pressure, reduces nervous anxiety, excessive irritability, restores lost sleep, improves blood circulation, and also helps to normalize heart function.

The listed effects of this drug develop very quickly (10-15 minutes after taking it) and persist for quite a long time - for 6-8 hours. The usual dosage is 15-30 drops on an empty stomach 2 or 3 times a day. In larger doses, Corvalol has a more pronounced hypnotic effect.

Low pulse requires a special approach to treatment, so when observing bradycardia, you should consult a doctor for diagnostics as soon as possible. Only the results of medical research will show the true cause of the development of this pathology and help determine effective methods of therapy.
