Sudden Cardiac Death

An 18 year old baseball player is hit in the chest by a regulation baseball at around 40 miles per hour and suffered cardiac arrest. He had no underlying heart disease and there was no structural damage to the chest wall, thoracic cavity, or heart itself.

Challenge: What happened?

Sudden Cardiac Death

This is commotio cordis which is sudden cardiac death, usually due to arrhythmia (ventricular fibrillation) in young athletes following low-impact precordial trauma with a projectile object.
