What is the harm of frequent ventricular premature beat

summary

In fact, premature beat is a very dangerous thing, even endangering our lives, but many people are not aware of this. Let's analyze the risk of premature beat.

What is the harm of frequent ventricular premature beat

First, ventricular tachycardia. Ventricular tachycardia refers to tachycardia originated from more than 3-5 wide abnormal QRS waves below the bifurcation of his bundle. It is similar to paroxysmal supraventricular tachycardia in form, but the symptoms are more serious. Children are restless, pale, and shortness of breath. Older children may complain of palpitations and precordial pain. Severe cases may have syncope, shock, and hyperemia The change of hemodynamics is mild in patients with transient attack, and significant hemodynamic change can occur in patients with attack lasting more than 24 hours. Physical examination shows that the heart rate is increased, often more than 150 beats / min, and the rhythm is regular, and the heart sound can be strong or weak.

Second, ventricular fibrillation (VF) is caused by many alternating waves of reentrant electrical activity. Its electrocardiogram shows a chaotic recording curve. VF can often be fatal unless it is defibrillated by direct current (it is difficult to defibrillate by chest thump or antiarrhythmic drugs).

Third, some people in the occurrence of frequent ventricular premature beats, may appear sudden cardiac death, sudden death generally refers to sudden, unexpected non-human death. This situation is mainly in the onset of an hour will find such a phenomenon, the latest is not more than 6 hours.

matters needing attention

People who have had premature beats should pay attention to control their emotions and not be excited. If they find that their heartbeat is irregular, they should go to the hospital for examination in time.
