Sudden cardiac arrest refers to a condition when the heartbeat of a person stops immediately. About 3.5 lacs of cardiac arrest incidents take place in the workplace or outside of a medical facility in the United States. Another aspect to worry about is that more than half of cardiac arrest patients do not receive basic life support or BLS before the arrival of the ambulance.
