Distal His bundle pacing is a feasible technique for correcting left bundle branch block with a low and stable capture threshold.
Distal His bundle pacing may correct LBBB at low stable thresholds; leaves open broader efficacy and requires prospective trials.
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.
