Progression of electrocardiogram tracings from the time of admission to immediately prior to transvenous pacer wire placement. EKG was repeated a few minutes later, showing complete heart block and idioventricular rhythm with a heart rate of 25 bmp immediately after starting a dobutamine infusion, at which point a transvenous pacer wire was emergently placed.
