case_images: (A) The fluoroscopic imaging associated with the implantation of LBBP. (B) LBB capture could be demonstrated by observing NSLBBP and SLBBP. (C) The postoperative electrocardiogram of the patient. LBB, left bundle branch; LVSP, left ventricular septum pacing; NSLBBP, nonselective left bundle branch pacing; SLBBP, selective left bundle branch pacing.

case_images: Ltd., Ningbo, Zhejiang, China), the 3830 lead (Medtronic, Minneapolis, MN) was implanted (Figure 1A). A threshold test was performed, and when the output was reduced to 1.5 V/0.5 ms, discrete component was displayed, confirming selective LBB capture (Figure 1B). Sheath angiography revealed that the lead depth was approximately 15 mm (Figure 1A). Postoperative electrocardiogram showed that the pacemaker worked well with a narrow QRS duration (Figure 1C).
