Definition & Operational Usage
Cardiac arrest is a medical emergency that occurs when the heart abruptly stops beating, leading to a cessation of blood flow to the brain and other vital organs. It is often caused by a heart attack, arrhythmias, or other cardiac conditions. Immediate intervention is critical to increase the chances of survival and minimize neurological damage.
