Commotio cordis is caused by the blunt impact of a hard object directly over the heart occurring during a specific window of ventricular repolarization leading to immediate collapse, ventricular fibrillation, and cardiac arrest. This episode focuses on risk factors and management of this rare but catastrophic injury.
