Cardiac arrest means the heart suddenly stops beating properly, so it cannot pump blood to the brain and other organs. It is a medical emergency and needs immediate help.
People use the term cardiac arrest when someone collapses unexpectedly, stops responding, and may not be breathing normally. In daily life, it is often used in serious news reports, hospital discussions, or emergency situations.
Meaning & Usage
Cardiac arrest is different from a heart attack. A heart attack is a blocked blood flow to the heart, while cardiac arrest is when the heart stops pumping altogether.
