Multiple endocardial countershocks applied during intraoperative endocardial implantable cardioverter-defibrillator testing for the purpose of defibrillation threshold determination resulted in detectable myocardial injury in 5 of 12 patients, as indicated by elevations in cardiac troponin I levels. This injury was not associated with acute changes on the surface electrocardiogram.
