Just a perfectly timed impact that sends the heart into chaos. Commotio cordis occurs when a blunt impact to the chest, strikes directly over the heart during a critical 20–30 millisecond window of the cardiac cycle. If that impact happens during ventricular repolarization (the upstroke of the T-wave), it can trigger ventricular fibri
