Figure 1
a. His bundle recording shows a sharp His bundle electrogram (black arrow). b. Pacing at that site resulted in nonselective His bundle capture (first two beats) transitioning with lower amplitudes to selective His bundle capture (last two beats). c. Posteroanterior fluoroscopic image showing the final position of the Biotronik Solia lead in the His bundle region (white arrow). The atrial lead was placed as a backup at the RV apex during ventricular lead implantation and afterward implanted in the right atrial appendage.
Figure 2
a. Baseline ECG. b. Left bundle branch pacing with a right bundle branch morphology in V1 and a short left ventricular activation time (79 msec). c. Left anterior oblique fluoroscopic image after contrast injection showing the depth of penetration into the septum (the atrial lead was placed as a backup at the RV apex during ventricular lead implantation and afterward implanted in the right atrial appendage). d. Echocardiographic parasternal short-axis image showing the lead tip reaching the left endocardium (white arrow).
