Asystole is one form of cardiac arrest (sudden cardiac death), but others include dangerous ventricular arrhythmias such as ventricular tachycardia or ventricular fibrillation.
Cardiac arrest refers to any situation in which the heart is not pumping
blood. This may occur with abnormal electrical activity in the heart in
which the heart is quivering ( ventricular fibrillation) or beating so
fast in can not pump blood effectively (Ventricular tachycardia,)
Asystole is a kind of cardiac arrest in which the heart is electrically
silent ( flat line) on EKG.
