Such poisoning does not always become obvious - sometimes it acquires a chronic course, and harmful substances accumulate in human tissues for years and even decades. How to determine the poisoning, and what measures need to be taken to eliminate its effects?

Heatstroke: First Aid

Thermal shock is hyperthermia accompanied by a systemic inflammatory reaction that causes multiple organ failure and often death. It is manifested by an increase in body temperature above 40 ° C and a mental disorder; sweating is often absent.

Heatstroke

Hyperthermia from heat exposure or heat stroke is a serious violation of the neurological and general functions of the human body, resulting from overheating of the entire body.

Heat stroke in a child

Thermal shock in a child is a condition that develops as a result of a pronounced violation of heat transfer processes due to unfavorable environmental conditions (high temperature and humidity) and is characterized by an extreme degree of body overheating with a violation of the functions of the central nervous system, cardiovascular system and severe water-electrolyte disorders.

Heat convulsions

Thermal convulsions are muscle-related muscle contractions that occur during or after physical exertion in conditions of high ambient temperature.

Heart valve replacement

The basic principles of technique and tactics of implantation of frame bioprostheses are similar to those when using mechanical valves. Unlike mechanical and skeletal biological prostheses, frameless bio-valves (xenografts, allografts, etc.) are not rigid, resistant to deformation structures and therefore their implantation can be accompanied by a change in both geometric and functional characteristics.

Heart Tumors: Causes, Symptoms, Diagnosis, Treatment

Tumors of the heart can be primary (benign or malignant) or metastatic (malignant). Mixoma, a benign primary tumor, is the most frequent neoplasm of the heart.

Heart rhythm disturbances in children

Heart rhythm disorders occupy one of the leading positions in the structure of morbidity and mortality of the child population. They can be presented as a primary pathology or develop against the background of an already existing disease, usually congenital heart disease. Cardiac arrhythmias often develop at the height of infectious diseases, complicate the diseases of other organs and body systems - CNS lesions, systemic connective tissue diseases, metabolic diseases, endocrine pathology.

Heart palpitations

The rate of heartbeats per minute for an adult varies between 60-80 times. A strong heartbeat can be said if this number exceeds 90-100 beats.

Heart failure: general information

Heart failure is a consequence of a violation of filling or contraction of the ventricles of the heart, which determines a decrease in pumping function of the heart, accompanied by typical symptoms: shortness of breath and rapid fatigue. Cardiomyopathy is a general term for primary cardiac muscle diseases.

Heart failure in the elderly

Heart failure in the elderly is due to a complex of structural and functional changes in various organs and systems. These changes, on the one hand, are inherent in an aging organism, serve as a manifestation of natural physiological aging, and on the other hand, are caused by diseases that existed in adulthood and middle age or joined in later periods.

Heart failure in children

The concept of heart failure can be defined as follows: a condition caused by violation of intracardiac and peripheral hemodynamics, associated with a decrease in contractility of the myocardium; a condition caused by the inability of the heart to translate the venous influx into an adequate cardiac output.

Heart failure

Cardiac arrest, or sudden cardiac death, can occur suddenly (within 24 hours of the onset of the first signs of the disease in physically active individuals), this happens outside the hospital, approximately 400,000 people a year (USA), 90% of the cases of cardiac arrest is cause of death.

Heart failure

The peculiarity of the heart muscles is their non-stop rhythmic contractions, which are the life-supporting function of the heart.

Heart disease pathology: causes, symptoms, diagnosis, treatment

In any heart valve, stenosis or insufficiency that causes hemodynamic changes may occur long before the onset of any symptoms. Most often, stenosis or insufficiency is detected in one valve, but multiple valve lesions are possible.

Heart breaks

Heart ruptures or myocardial ruptures are observed in 2-6% of all myocardial infarction cases with ST segment elevation. This is the second most frequent cause of death in hospital patients. Usually heart ruptures occur during the first week of the disease, but in some cases are observed later (up to the 14th day).

Headache of tension

Tension headache is the predominant form of primary headache, manifested by cephalic episodes lasting from several minutes to several days. The pain is usually bilateral, compressive or pressing, light or moderate intensity, does not increase with normal physical activity, is not accompanied by nausea, but photophobia is possible.

Headache after lumbar puncture

Headache can be the result of a decrease in CSF volume and pressure due to lumbar puncture or as a result of liquorrhea.

Head pediculosis. Causes. Symptoms. Diagnostics. Treatment

Head pediculosis (synonyms: pediculosis, lice) is a disease caused by head louse that parasitizes on the scalp and neck.

Head injury

A head injury is a trauma to the soft tissues of the skull, most often closed. How to recognize a head injury? How is the head contusion manifested? What if you got a head injury?
