Chest Compressions Count for Sudden Cardiac Arrest

By James Frederick, PA-C, Emergency Department

Imagine a young adult who exercises regularly, eats the right foods, and is in excellent shape. His heart suddenly stops, and you instantly think “heart attack,” but sudden cardiac arrest (SCA) is different from a heart attack. Think of a heart attack as a plumbing problem of the heart; sudden cardiac arrest is an electrical prob­lem of the heart which keeps it from pumping prop­erly. A person who has suffered SCA will suddenly collapse and lose consciousness, with no pulse or breathing.

If you are with someone who experiences SCA, call 911 right away and begin CPR or just chest compressions alone until emergency personnel ar­rive. Push hard and fast on the person’s chest at the rate of 100-120 compressions a minute (or to the familiar tune of the Bee Gees song “Stayin’ Alive”). Without immediate chest compressions or a shock from an automated defibrillator (AED), the SCA victim most often dies within minutes causing “sudden cardiac death.”

Although SCA is sudden and unexpected, there are factors which may heighten your risk including a previous sudden cardiac arrest or heart attack, hyper­thyroidism, drug abuse, smoking, high blood pressure, diabetes, family history, and more. Heart problems leading to cardiac arrest can produce signs that should not be ignored. These symptoms may consist of chest pain and black­outs (especially with exertion), fainting, fluttering of the heart, becoming easily fatigued, weakness, dizziness, and shortness of breath. Pay close attention to any of these symptoms and consult with your doctor.

There is no sure way to know if or when SCA will happen to you, so the best thing to do is try to prevent it by lowering your risk as much as possible. You can accomplish this by eating a nutritious and balanced diet, being physically active, not smoking or abusing drugs or alcohol and get­ting regular medical checkups. All these things and more can keep your heart healthy and even save your life.

It’s common to think, “This won’t happen to me!” You may be right, but it may happen to someone next to you. Remember the first minutes count the most so take action imme­diately. Call 911, or have someone call for you while you begin CPR or chest compressions. If an AED is available, the best chance for rescu­ing the person involves defibrilla­tion with that device, which can help restart the heart. Advanced medical treatment will continue in the ambu­lance and closest emergency room.
