About the Data

Cardiac arrest occurs when the heart suddenly stops beating due to a lethal heart rhythm. Without immediate treatment, cardiac arrest can lead to death within minutes. Bystanders who witness a cardiac arrest or find a person who has arrested can increase the chances of survival by immediately calling 911, beginning CPR, and applying an AED, if one is available. Knowing how to respond to an emergency, such as cardiac arrest, can save a life.
