Why do cardiac arrests happen?

With cardiac arrest, abnormal, rapid impulses abruptly override the normal electrical impulses that start your heartbeat. When your heart isn’t beating, there’s no way to get oxygen-rich blood to the rest of your body.

Cardiac arrest vs. heart attack

Here’s how cardiac arrest and heart attack are different:

  • Cardiac arrest happens when rapid, abnormal impulses override your heart’s natural rhythm. It’s an electrical issue.
  • Heart attack occurs when a clogged artery disrupts blood flow to your heart. A heart attack is a common cause of cardiac arrest.
