UNDERSTANDING SUDDEN CARDIAC ARREST

Sudden Cardiac Arrest (SCA)

The Difference between Sudden Cardiac Arrest and a Heart Attack

Sudden cardiac arrest is often confused with a heart attack. Although a prior heart attack increases one’s risk for sudden cardiac arrest, the two are quite different, with distinct risk factors, treatment options and outcomes.

Anatomy of a Heart Attack

A circulation problem of the heart causes a heart attack when one or more of the arteries delivering blood to the heart are blocked. Oxygen in the blood cannot reach the heart muscle, and the heart muscle becomes damaged. You can think of a heart attack as a “plumbing problem” in the heart.

This damage to the heart muscle can lead to disturbances of the heart’s electrical system. And a malfunction of the heart’s electrical system may cause dangerously fast heart rhythms that can lead to sudden cardiac arrest.

Anatomy of Sudden Cardiac Arrest

In contrast to a heart attack, sudden cardiac arrest is caused by an “electrical problem” in the heart. It occurs when the heart’s lower chambers (ventricles) suddenly develop a rapid, irregular rhythm (ventricular fibrillation) causing the ventricles to quiver rather than contract. The chaotic quivering motion of the ventricles renders the heart an ineffective pump that can no longer supply the body and brain with oxygen.

Within seconds, the person loses consciousness and has no pulse. Only immediate emergency treatment, such as cardiopulmonary resuscitation (CPR) and external defibrillation, can prevent death from sudden cardiac arrest. Time is key to surviving sudden cardiac arrest, with chances of survival decreasing about 10 percent every minute without defibrillation. The American Heart Association recommends defibrillation within five minutes of collapse or sooner.

  1. The way you described the differences between a heart attack and sudden cardiac arrest make them very easy to understand. I had not hear the “plumbing” and “electrical” references used before. Putting it in “home repair terms” may get through to more people. Good post.

    • Thank you for taking the time to read our post. And thanks for the valuable feedback in terms of the wording we chose. This kind of feedback helps us guage our ability to make sense to the public, which assists in our mission to help raise awareness of the need for early detection of heart abnormalities via screenings. ~Many Blessings.
