Tachycardia is a kind of arrhythmia, characterized by a heart rate of more than 90 beats per minute. A variant of the norm, tachycardia is considered as an increase in the physical or emotional load. Pathological tachycardia a consequence of diseases of the cardiovascular or other systems. It is manifested by palpitation, pulsation of the vessels of the neck, anxiety, dizziness, fainting.
Classification of tachycardia
Taking into account the reasons that caused the rapidity of heartbeats, tachycardia is distinguished physiological, which arises in the normal functioning of the heart as an adequate response of the organism to certain factors, and pathological, developing at rest due to congenital or acquired cardiac or other pathology.
Pathological tachycardia is a dangerous symptom, since it leads to a decrease in the volume of blood outflow and other disorders of intracardiac hemodynamics. With too frequent heart beat, the ventricles do not have time to fill with blood, cardiac output decreases, blood pressure decreases, blood and oxygen flow to the organs, including to the heart, weaken.
Causes of sinus tachycardia
Sinus tachycardia occurs in different age groups, more often in healthy people, as well as among patients, with cardiac and other diseases. The emergence of sinus tachycardia is facilitated by intracardial (cardiac), or extracardiac (non-cardiac) etiological factors. Sinus tachycardia in patients with cardiovascular disease is most often an early symptom of heart failure or left ventricular dysfunction.
Treatment of sinus tachycardia
It is necessary to eliminate factors contributing to increased heart rate: exclude caffeine-containing beverages (tea, coffee), nicotine, alcohol, spicy food, chocolate; protect yourself from psycho-emotional and physical overload. With physiological sinus tachycardia, no treatment is required.
Treatment of pathological tachycardia should be aimed at eliminating the underlying disease. With extracardiac sinus tachycardia of a neurogenic nature, the patient needs consultation of a neurologist. In the treatment use psychotherapy and sedatives (luminal, tranquilizers and neuroleptics: mebicar, diazepam). In the case of reflex tachycardia (with hypovolemia) and compensatory tachycardia (with anemia, hyperthyroidism), it is necessary to eliminate the causes that caused them. Otherwise, therapy aimed at reducing heart rate, can lead to a sharp drop in blood pressure and aggravate hemodynamic disorders.
