Cardiac Arrest

The sudden cessation of the heart’s contractions which circulate blood to the body and brain, also known as sudden cardiac arrest. Cardiac arrest usually occurs as a result of a rapid ventricular rhythm (ventricular tachycardia) or a chaotic one (ventricular fibrillation or cardiac standstill). Death occurs within minutes unless cardiopulmonary resuscitation and/or defibrillation devices are available.
