ABOUT CARDIAC ARREST

1 A cardiac arrest is different from a heart attack. Cardiac arrest is caused by irregular heartbeats while a heart attack happens when there is a blockage in a coronary artery.

2 The victim would often be unconscious, have no pulse and may be gasping or not breathing at all.

3 Cardiac arrest can happen suddenly, without any warning signs and symptoms. It can be triggered by various heart conditions including a heart attack.

4 Each year, there are about 1,800 cases of cardiac arrest that happen outside of a hospital. Between July 2012 and February last year, about 4.6 per cent of cardiac arrest victims survived.

5 Providing early CPR is key as the survival rate decreases by 10 per cent every minute between collapse and resuscitation. Administering the AED within four minutes of collapse could increase survival by up to 90 per cent.
