What is the sudden, unexpected stopping of the heart called?

Explanation:
Cardiac arrest is the sudden stoppage of the heart’s pumping action. When this happens, blood stops flowing to the brain and other organs, leading to immediate loss of consciousness, no pulse, and no breathing. It’s a medical emergency requiring rapid action: call for help right away and start CPR, using an AED as soon as it’s available. This differs from a heart attack, which is a blockage that can damage heart muscle while the heart may still beat; an arrhythmia is an abnormal heart rhythm and can sometimes lead to arrest but isn’t the event of the heart stopping itself; a stroke is a brain event caused by disrupted blood flow, not the heart.
