Alexander Postalian, MD, Mohammad Saeed, MD, J. Alberto Lopez, MD, and Yochai Birnbaum, MD

A 93-year-old woman with no symptoms was admitted to the hospital for a pacemaker generator exchange. She had a history of ischemic cardiomyopathy and was taking optimal medical therapy. She had also experienced paroxysmal atrial arrhythmia, which had been treated with atrioventricular node ablation and dual-chamber permanent pacemaker implantation. Upon her arrival, a 12-lead electrocardiogram was obtained (Fig. 1).
