Answer: Commotio Cordis is sudden cardiac death due to chest wall impact, usually over the cardiac region. Commotio Cordis is a Latin word that means "agitation of the heart."
The objective of this question is to highlight the fact that despite not well-known, this is one of the very common causes of sudden cardiac death in young athletes. This may be due to projectile balls like in baseball, cricket, or hockey or due to the impact of a body part of other athletes in contact sports like in American football.
Despite immediate CPR and medical treatment, mortality is very high. It is particularly fatal if the timing of impact corresponds with T-wave, conditioning "R-on-T phenomenon" resulting in ventricular fibrillation.
