SCA is a sudden and unexpected pulseless condition attributed to cessation of cardiac mechanical activity. It is usually caused by ventricular fibrillation, an abnormality in the heartâs electrical system. When SCA occurs, blood stops flowing to the brain, the heart, and the rest of the body, and the person collapses.
About Sudden Cardiac Arrest. More than 350,000 deaths occur each year as a result of sudden cardiac arrest. SCA claims one life every two minutes, taking more lives each year than breast cancer, lung cancer, or AIDS. To decrease the death toll from SCA, it is important to understand what SCA is, what warning signs are, and how to respond and prevent SCA from occurring.
