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.
