Is it true that Commotio cordis is a disruption of heart rhythm caused by a blow to the precordial region at a critical instant during the heartbeat cycle?

Yes. Commotio cordis is well-documented in medical literature as a disruption of heart rhythm, specifically ventricular fibrillation, caused by a blunt blow to the precordial region during a vulnerable electrical window in the cardiac cycle.
