From: Two cases of hemodynamic improvement by modulation of atrioventricular delay in cardiac operations

Fig. 2

Electrocardiographic changes at each indicated point (AE) during anesthesia in case 2. The pacing mode and arterial blood pressure at each point are shown. The QRS width changes from wide to narrow by adjusting the atrioventricular delay (BC). Ventricular pacing is activated due to atrioventricular block immediately after weaning from the cardiopulmonary bypass (D), but atrioventricular conduction improves at the end of the operation (E). PM pacemaker, ABP arterial blood pressure, AV atrioventricular, CPB cardiopulmonary bypass
