Sudden cardiac arrest explained in interactive 3D: how it differs from a heart attack, and the chain of survival — call for help, CPR, and using an AED (defibrillator) — plus ICDs for those at risk.
Cardiac arrest is not a heart attack — the heart’s rhythm collapses and it stops. Learn the difference, and the chain of survival: call for help, push hard and fast on the chest, use an AED.
