The QRS morphology in left bundle branch area pacing (LBBAP) is utilized to assess procedural success and to confirm left bundle branch (LBB) capture.
We present a case in which the QRS morphology of the left bundle branch pacing (LBBP) changed during the procedure despite the maintenance of LBB capture throughout.
This case highlights the necessity for operators to be aware of this pitfall and raises potential questions regarding the determination of LBB capture.
左束支区域起搏（LBBAP）中的QRS波形态用于评估手术成功率并确认左束支（LBB）捕捉情况。
我们报告一例尽管在整个手术过程中维持了左束支捕捉，但左束支起搏（LBBP）的QRS波形态仍发生改变的病例。
该病例凸显了术者了解这一陷阱的必要性，并引发了有关确定左束支捕捉的潜在问题。
