Ventricular fibrillation (V-fib or VF) is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly. Ventricular fibrillation is the most commonly identified arrhythmia in cardiac arrest patients. While there is some activity, the lay person is usu...

is an irregular twitching of the heart muscle wall, interfering with the normal rhythm of the ventricles. The electrical impulses may become chaotic, so the heart muscles do not respond correctly. It is often corrected by early use of a defibrillator. See Cardiac arrest, Automatic external defibrillator, and Supraventricular tachycardia.

Ventricular fibrillation: An abnormal irregular heart rhythm whereby there are very rapid uncoordinated fluttering contractions of the lower chambers (ventricles) of the heart. Ventricular fibrillation disrupts the synchrony between the heartbeat and the pulse beat. Ventricular fibrillation is most commonly associated with heart attacks or scarring...
