Each year sudden cardiac arrest (SCA) strikes approximately a quarter-million people in the U.S. alone. The majority of these people have no warning, since they show no prior symptoms. And, sadly, fewer than 5% survive, often because emergency medical services cannot reach them in time. When sudden cardiac arrest strikes, the electrical system of the heart short-circuits, most often causing an abnormal rhythm known as ventricular fibrillation. Lacking proper blood flow, the person loses consciousness, stops breathing, and will die unless promptly treated. CPR (cardiopulmonary resuscitation) can help a person in cardiac arrest, but it alone cannot save lives. A "shock" from a defibrillator defibrillation therapy is needed to restore the heart's normal pumping rhythm. A victim's best chanceof surviving SCA is to receive that shock within 5 minutes of collapse.
