What Is Ventricular Arrhythmia?
Ventricular arrhythmia is an irregular heart rhythm that occurs in the ventricles, or lower chambers, of the heart. There are three types of ventricular arrhythmias: ventricular tachycardia, ventricular barycardia and ventricular fibrillation. Tachycardia indicates that the heart is beating too fast — generally more than 100 beats per minute — and barycardia means the beat is too slow, or less than 60 beats per minute. In ventricular fibrillation, the heart beats very fast and without a coordinated rhythm.
