Figure 1
A: A peripheral venogram demonstrating a subtotally occluded left subclavian vein with distal reconstitution primarily via bridging collaterals (anteroposterior projection). B: A balloon occlusive coronary sinus venogram revealing a small and stenotic posterolateral branch and a smaller anterolateral branch into which leads were unable to delivered (right anterior oblique projection).

Figure 2
Twelve-lead electrocardiogram demonstrating the pre (A) and post (B) His bundle pacing QRS morphologies. The QRS duration in lead V1 with His bundle pacing measures 84 ms.
Figure 3
Figure 3
Lateral chest radiograph revealing the positions of the 3 leads: (1) right atrium (pacing lead), (2) His bundle region (pacing lead), and (3) right ventricular apex (implantable cardioverter-defibrillator lead).
