According to estimates from various researches 60 per cent of deaths in hospitals due to myocardial infarctions (MI) are sudden. But the majority of sudden cardiac events happen outside the hospital, usually at home. A sudden cardiac arrest is when the heart stops beating due to a disruption in the electrical impulses.
In India, the reaction time to any medical emergency is known to be lengthier compared to the West. Around 95 per cent of the patients who die after a sudden cardiac arrest could be saved if they are given defibrillation within four to six minutes of suffering the attack.
