[Causes and symptoms
This can be caused by a variety of causes: a lifestyle (smoking, alcohol, excessive caffeine consumption, overeating, etc.), heart disease, insect bites, hormonal disorders (especially in women), frequent stress, nerve stress, arrhythmia can be toxic and medications.
Arrythmia-causing drugs:
- cardiac glycosides
- beta-blockers
- clonidine
- reserpine
- adrenaline, caffeine, atropine, as well as stimulants of the nervous system (amphetamine)
- drugs for the treatment of psychosis or depression, often drugs from arrhythmia, written by a specialist from one type, provoke the development of another type of arrhythmia.
Allocate sinus, atrial fibrillation, extrasitolia, cardiac blockade, paroxysmal tachycardia.
Cardiac glycosides (strophanthin, digoxin, etc.) in higher doses usually accumulate in the body, which leads to a decrease in the heart rate. These drugs have a glycosidic structure and have selective cardiotonic action.
Beta-adrenoblockers (atenolol, metoprolol) reduce the heart rate. These drugs block beta-adrenoreceptors and are conditionally divided into two groups.
Preparations of the first group (blockers of β1-adrenergic receptors) basically reduce the frequency of heart beats, reduce the rhythm, inhibit cardiac conduction).
Preparations from the second group (β1-adrenoreceptors and β2-adrenergic receptors) increase the tone of smooth muscles (uterus during pregnancy, bronchi, arterioles, contributes to an increase in the total peripheral resistance of blood vessels.
Beta-blockers are often used in diseases such as cardiac arrhythmia, high blood pressure, and also to prevent the recurrence of myocardial infarction.
Clonidine, reserpine are used mainly to treat high blood pressure, can cause a decrease in heart rate.
Preparations Caffeine, Adrenaline, Atropine cause an increase in the frequency of the heart rhythm.
Treatment of drug arrhythmia
As a rule, arrhythmia occurs when an overdose of certain drugs or intolerance of certain drugs.
This violation is a danger to human life and can lead to acute or chronic heart failure, cardiac arrest (clinical death).
When arrhythmia caused by the abuse of certain medications, you should stop taking medication, take any antiarrhythmic drugs without prescribing the doctor is undesirable, since medication is possible.
In some cases sedatives are prescribed (Persen, Sanosan, Antares), which also reduce nervousness, excitability, improve sleep.
If an arrhythmia is detected, the patient is assigned a checkup for possible development of coronary heart disease, disruption of heart valves, heart failure.
