differences between a heart attack cardiac arrest and stroke

Heart Attack:

A heart attack is a circulation disorder.

Sometimes, the flow of oxygen-rich blood to a portion of the heart muscle is blocked. If the blood flow is not restored, the muscle begins to die due to a lack of oxygen. This causes a heart attack.

In a heart attack, the heart continues to beat.

Cardiac Arrest:

A cardiac arrest is an “electrical” disorder.

When the electrical activity of your heart experiences chaos, it causes the heart to start beating irregularly, and abruptly stop pumping blood through the body. This is a cardiac arrest.

In a cardiac arrest, the heart stops beating completely.


A stroke is a brain disorder.
