Is it true that Commotio cordis is caused by mechanical damage to the heart muscle or surrounding organs?

No. Commotio cordis is defined as sudden cardiac arrest caused by a precordial impact that triggers a lethal arrhythmia (such as ventricular fibrillation) via mechanoelectrical coupling, characteristically occurring in the absence of structural heart damage or trauma to the heart muscle itself.

Verdict: REFUTED · 0 sources for, 4 against · Last checked

The analysis

The claim states that commotio cordis is caused by mechanical damage to the heart muscle or surrounding organs. Multiple specialized reviews and case reports on commotio cordis (e.g., Papers 0, 4, 6, and 9) explicitly state that the condition occurs in the absence of structural heart disease or gross mechanical damage to the heart muscle, being instead an electrical phenomenon (arrhythmia) triggered by precise timing of the impact relative to the cardiac cycle. Therefore, the claim is refuted.
