L-Type Calcium Channels Do Not Play a Critical Role in Chest Blow Induced Ventricular Fibrillation: Commotio Cordis

Figure 3

Bar graph of the results of 62 impacts to 12 animals with 36 impacts in 6 control animals and 26 impacts in 6 animals given verapamil. There was no difference in the endpoints of ventricular fibrillation (VF) or the combined endpoint of VF + nonsustained VF. Verapamil administration did decrease the severity of ST segment elevation and the induction of a bundle branch block (BBB).
