What's the difference between cardiac arrest and heart attack. While a heart attack is a plumbing problem a cardiac arrest is an electrical problem. The difference being that a heart attack is a slow though agonizing process while a cardiac arrest is sudden. More often though symptoms start slowly and persist for hours days or weeks before a heart attack.
The critical difference between a cardiac arrest vs a heart attack is that the heart shuts down following cardiac arrest whereas after a heart attack it can still pump.

Cardiac arrest happens suddenly and often involves a loss of responsiveness. But the two entities are not the same thing. A heart attack is when blood flow to the heart is blocked and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly.
Heart attacks increase the risk of cardiac arrest. Heart attack symptoms often include shortness of breath pain in the chest or arm nausea or vomiting light-headedness or fatigue. A heart attack is a heart disease which happens when one of the arteries supplying blood to the heart muscles gets blocked suddenly by a blood clot over an ulcerated atheromatous plaque.

A heart attack usually occurs when blood supply to the heart stops which causes the portion of the heart to stop beating making it to slowly die.

Cardiac arrests and heart attacks are inextricably linked because SCAs can occur during or after a heart attack. The most straightforward way to distinguish between these two heart conditions is to remember that a heart attack is a circulation problem while cardiac arrest is an electrical problem. Heart attack is caused.
In fact most sudden cardiac arrests occur after a heart attack or during recovery.
