Figure 1 Telemetry and initial interrogation. A: The telemetry strip shows frequent pauses and pacing inhibition. B: Device electrograms before and during a ventricular sensing amplitude test include low-amplitude signals on the ventricular channel that inhibit pacing and are inappropriately sensed as intrinsic beats during the sensing test. The magnified box shows a far-field ventricular electrogram of amplitude 0.7 mV that is inappropriately sensed after a ventricular paced beat. The atrial electrograms (not included) showed atrial fibrillation.

Figure 2 Three-dimensional (3D) imaging of the implantable cardioverter-defibrillator leads and left ventricular assist device. The 3D reconstruction of the chest computed tomography (CT) (A) and the corresponding 2-dimensional CT image in the axial plane (B) demonstrate the close proximity of the right ventricular lead tip to left ventricular apical cannula.

Figure 3 Resolution with advanced device programming. A: The algorithm decouples the right ventricular pacing and defibrillation sensitivities. B: The ventricular paced events occur shortly after inappropriately sensed events, which are ignored only for the purposes of pacing.
