Cardiac Arrest vs. Heart Attack

Heart attacks and cardiac arrest are not the same thing.

Heart Attack:
  • Occurs when blood flow to part of the heart muscle is blocked by a clot.
  • The longer the person with a heart attack goes without treatment, the greater the damage to the heart muscle.
  • Occasionally, the damaged heart muscle triggers an abnormal rhythm that can lead to cardiac arrest.
Cardiac Arrest:
  • Occurs due to an abnormal heart rhythm.
  • The abnormal rhythm causes the heart to quiver so that it can no longer pump blood to the brain, lungs, and other organs.
  • Within seconds, the person becomes unresponsive and is not breathing or is only gasping.
  • Death occurs within minutes if the victim does not receive lifesaving treatment.
