A 65 year-old woman presented with two episodes of syncope. She developed paroxysmal atrioventricular (AV) block when an ECG was being recorded (Fig. 1). She developed at least one other similar episode. Then, she developed complete AV block with a stable escape ventricular rhythm of about 30 bpm during which an atrial premature beat was conducted (Fig. 2). Isoproterenol was administered which ...
