The Mechanism of Commotio Cordis

The video explains commotio cordis, a rare cardiac event caused by a blunt force to the chest, leading to cardiac arrest. It details the cardiac action potential phases and how a blow during the T wave can induce ventricular fibrillation. The video also discusses the risk factors, such as high-impact sports, and the rarity of the event due to specific timing and location requirements.

Discuss the potential outcomes of commotio cordis and the importance of timely defibrillation.
