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.
A cardiac arrest is an “electrical” disorder.
