WebA ventricular arrhythmia is an arrhythmia that occurs when another area within the lower chambers of the heart (ventricles) takes over the function of driving the heart rate. Arrhythmias can also be classified as slow (bradyarrhythmia) or fast (tachyarrhythmia). "Brady-" means slow, while "tachy-" means fast. WebArrhythmias and direct myocardial damage – high voltage or DC usually causes asystole, whilst AC usually causes VF. VF is the most common fatal arrhythmia, occurring in up to 60% of patients where the current pathway travels from one hand to the other (i.e. the pathway is transthoracic).
