This case demonstrates the feasibility of placing the pacing lead helix at the His bundle distal to the region of left bundle branch block and reveals three types of electrocardiographic characteristics of distal His bundle pacing during correction of left bundle branch block in a patient. As the pacing lead helix was placed distal to the block, left bundle branch block correction was achieved by pacing with a low and stable capture threshold.
该病例展示了将起搏导线螺旋电极置于左束支传导阻滞区域远端的希氏束处的可行性，并揭示了一名患者在纠正左束支传导阻滞期间远端希氏束起搏的三种心电图特征类型。由于起搏导线螺旋电极置于阻滞远端，通过低且稳定的夺获阈值起搏实现了左束支传导阻滞的纠正。
