Fibrillation, ventricular
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 commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. Ventricular fibrillation is life threatening.
