Commotio cordis (Latin agitation of the heart) is an often lethal disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical time during the cycle of a heart beat causing cardiac arrest. It is a form of ventricular fibrillation (V-Fib) not mechanical damage to the heart muscle or surrounding organs and not the result of heart disease. The fatality rate is about 65%.
