Ventricular tachycardia is a rapid heartbeat that arises from improper electrical activity that starts in the bottom chambers of the heart called the ventricles and these ventricles are the main pumping chambers of the heart. This is potentially life-threatening arrhythmia because it can cause low blood pressure and may lead to sudden death ventricular fibrillation and asystole, VT is a pulse rate of more than 100 beats per minute, with at least 3 irregular heartbeats in a row.

The condition can develop as an early or late complication of a heart attack. It may also occur in people with:
