What is ventricular tachycardia?

The heart has two upper chambers and two chambers of the heart - the latter is also called the ventricles. Tachycardia means a rapid heart rate; that is, rapid pulse. A heart attack usually starts with an area of a right atrium sends out an electrical impulse that spreads down the heart's electrical conduction system of heart chambers. When the impulse reaches the ventricles, then pull themselves together.

An electrical impulse can also occur elsewhere in the conduction system. When it occurs in the chambers of the heart, we call the resulting contraction of the ventricles of a ventricular extrasystole (an additional stroke, extra strokes). Ventricular tachycardia is defined as 3 or more consecutive ventricular extrasystoles. In ventricular tachycardia, the pulse / heart rate usually stays at 160-240 per minute.

Ventricular tachyarrhythmias can be divided into non-sustained (<30 and="and" br="br" persistent.="persistent." seconds="seconds">
ventricular tachycardia definition

Short episodes of ventricular tachycardia occur frequently in the first 48 hours of a heart attack. Ventricular extrasystoles in itself is a common phenomenon that generally does not require treatment.
