What Happens in a Sudden Cardiac Arrest?
Victims of SCA are unresponsive, lose consciousness, stop breathing, and have no pulse. Most often, the victim is suffering from a heart rhythm disorder called ventricular fibrillation (VF). In this case, the victim needs CPR and defibrillation-an electric shock to correct the heart’s rhythm-as soon as possible. VF can happen to anyone-even someone who appears perfectly healthy.
