It refers to the condition where the heart stops pumping blood and there is no blood circulation. A cardiac arrest is different from a heart attack in the sense that in a heart attack (myocardial infarction) the blood flow to the heart is impaired. It requires immediate medical attention and can be reversed in certain situations if treated quickly. Cardiopulmonary resuscitation (CPR) to restart blood circulation followed by defibrillation (giving an electric shock) to restart the natural cardiac pacemaker is the usual procedure to deal with cardiac arrests.
