Electrocardiogram

Electrocardiogram (ECG) findings in commotio cordis can vary depending on the timing of the ECG recording and the presence of arrhythmias. The most common rhythm observed in commotio cordis cases is ventricular fibrillation (VF). Other arrhythmias such as complete heart block, idioventricular rhythm, and atrial fibrillation have also been reported.
