Cardiac arrest is the sudden loss of cardiac function, when the heart abruptly stops beating. Unless resuscitative efforts are begun immediately, cardiac arrest leads to death within a few minutes.

A cardiac arrest is different to a heart attack. In a cardiac arrest the heart actually stops beating; whereas in a heart attack the heart normally continues to beat even though the blood supply to the heart is disrupted. heart attack occurs when the blood supply to part of the heart stops and thus causes a section of the heart muscle to begin to die; whereas a cardiac arrest occurs when the heart stops beating as a whole. There are various symptoms of a heart attack.
