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.
If an AED is available, it should be applied. The best chance of SCA survival is prompt recognition, and a planned emergency response with CPR and AED use. If sudden cardiac arrest is not treated within minutes to establish a normal heart rhythm, a person will die.
