Contrary to what the movies might have us believe, a cardiac arrest and a heart attack are two very different things.
In cardiac arrest the heart stops abruptly. A heart attack might or might not results in cardiac arrest.
If you witnessed a cardiac arrest - would you know what to do?
With tomorrow being International Restart a Heart Day, Te Puke St John chairwoman Lyn Govenlock says it is important to know two things - to start Cardiopulmonary Resuscitation (CPR) straight away and, if possible, initiate a ''shock'' with an Automated External Defibrillator (AED).
There is a St John app available that offers instruction on how to perform CPR and also an AED locator app - both available as free downloads.
