What Is a Cardiac Arrest?

difibrillattorI couldn’t let National Sudden Cardiac Arrest (SCA) month go by without a mention. According to the American Heart Association (AHA), over 90% of those suffering a cardiac arrest outside of a hospital died. The awareness campaign wants to improve those odds.

Did the campaign work? Do you now know the difference between a heart attack and a cardiac arrest?  Don’t worry, I have experienced both and I didn’t know the difference for quite a while afterwards.

Plumbing vs. Electrical

A heart attack is plumbing – your arteries are blocked.  A cardiac arrest is electrical – your heart stops beating (think death).  Here are the main differences:

  1. A heart attack occurs when a blocked artery prevents blood from reaching a section of the heart.
  2. Symptoms may be immediate and intense, or they may start slowly and persist for hours, days or weeks before the attack occurs.
  3. The heart usually does not stop beating during a heart attack.
  4. Cardiac arrest occurs suddenly and often without warning.   Cardiac arrest is triggered by an electrical malfunction in the heart that causes an irregular heart attack vs cardiac arrestheartbeat.

How To Save a Life

What should you do if you think someone might be in cardiac arrest? The AHA recommends the following:

  1. Yell for help. Tell someone to call 911 and someone else to find an automated external defibrillator (AED).
  2. Check breathing – if the person is not breathing, start CPR.
  3. Begin chest compressions. Use the AED if available.
  4. Keep up the chest compressions until help arrives.

Immediate assistance is the difference between life and death for someone in cardiac arrest. You can read more about the campaign and sudden cardiac arrest here.
