Figure 1
Twelve-lead electrocardiogram showing atrial fibrillation and ventricular pacing at a rate of 48 beats/min.
Figure 2
Figure 2
Permanent pacemaker interrogation showing inappropriate ventricular sensing at the T waves, confirming T-wave oversensing that caused a delay in ventricular pacing.
Figure 3
Figure 3
Hemodynamics review chart showing the improvement of cardiac index (C.I.) from 1.68 to 2.36 L/min/m2 after abolition of the T-wave oversensing and restoration of an appropriate ventricular pacing.
