The difference between a Heart Attack & Cardiac Arrest:
Heart attack happens when blood flow to the heart is blocked, usually by a clot. The heart usually keeps beating, but part of it is starved of oxygen.
Cardiac arrest happens when the heart suddenly stops beating. This stops blood from flowing to the brain and other organs.
In short:
Heart attack = blood flow problem.
Cardiac arrest = electrical problem (heart stops).
A heart attack can lead to cardiac arrest if not treated quickly.
