Ventricular tachycardia exacerbated by left bundle branch area pacing.

Since 2017 after Huang et al suggested direct capture of the left bundle branch (LBB) by placing the lead deep inside the proximal interventricular septum1, left bundle branch area pacing (LBBAP) has gained popularity due to its easier application, lower and stable pacing thresholds, higher sensing amplitude, and more stable lead position, when compared with His bundle pacing. Here, we describe a rare case of ventricular tachycardia (VT) that developed after implantation of a LBBAP lead and necessitated both catheter ablation and lead removal.
