This sudden paroxysmal tachycardia.

Paroxysmal tachycardia is one of the many variants of cardiac arrhythmias, in which there is a sudden change in cardiac activity toward an increase in the number of cardiac contractions. The number of cuts can be from 140 to 200 beats per minute.

As a result of changes in the frequency of contractile movements, various hemodynamic disorders occur, which adversely affect the patient's well-being. During an attack, the diastole phase is disrupted, it shortens, as a result of this the ventricles of the heart are not enough, and with strong paroxysm generally lean with blood. All this causes a reduction in indicators such as stroke and minute volume of blood circulation. The organism ceases to be saturated with blood, its acute shortage is felt by the anatomical formations remote from the myocardium - the brain, kidneys, intestines, lungs. Even the heart muscle itself feels a sharp deficit of blood and dissolved gases and nutrients in it. The longer the paroxysmal tachycardia, the worse the clinical picture will be. Because of the narrowing of the peripheral vessels, blood flow is redistributed, which tries to compensate centralized circulation and increase the falling pressure. If the compensatory mechanisms fail, cardiac shock, an attack of angina pectoris, a myocardial infarction can occur. The blood flow in the coronary arteries feeding the heart sharply changes. Change in blood circulation in the brain structures leads to syncope, in renal tissue - to anuria. Long-term paroxysmal tachycardia can even be the cause of necrosis in the intestine in very severe cases.

The onset of an attack of cardiac paroxysm does not pass unnoticed for the patients themselves. They can say with certainty when it began, because At this moment, they feel a sharp push in the area behind the breastbone, and when it is over, tk. The end of the attack sharply breaks the heartbeat. A typical picture of the attack: the patients look frightened, pale, with a cold, sticky sweat. They can rush during paroxysms, not finding a place because of the anxiety that has engulfed them. Jugular veins swell and noticeably pulsate in time with the pulse.

If the paroxysmal tachycardia is started by the patients on their own, then soon there is heart failure, which progresses and does not respond to the medicinal effects. Usually two main forms of such arrhythmias are distinguished: supraventricular and ventricular. Nadzheludochkovaya paroxysmal tachycardia has a lot of options associated with the sudden emergence of pathological foci of automatism, as well as reciprocal excitations. When arrhythmia is very dangerous, when the atrium and ventricles begin to shrink asynchronously, heart failure can quickly and refractorily treat.

Paroxysmal tachycardia, the treatment of which must be performed as early as possible, has a number of characteristics that are related to the nature and the specific type of rhythm disturbance. Sometimes patients themselves can stop their suddenly emerging symptom. It is associated with a reflex action on the vagus nerve. You can throw your head back, click on the area of the carotid projection, try to breathe out or inhale with a closed voice gap, press on the eyeballs, inflate the rubber balloon, ball or wipe the face with ice cubes. It is especially good to carry out reflex actions after preliminary administration of beta-blockers, which significantly increase the effectiveness of all these methods. Drug therapy is carried out only under the supervision of the attending physician.
