Left Bundle Branch Pacing Guided by Continuous Pacing Technique That Can Monitor Electrocardiograms and Electrograms in Real Time: A Technical Report

      Left bundle branch pacing (LBBP) can achieve the physiological characteristics of pacing and provides a low and stable threshold compared with His bundle pacing.

      A novel pacing strategy with low and stable output: pacing the left bundle branch immediately beyond the conduction block.
      However, the inability to monitor paced QRS characteristics and impedance in real time to avoid perforation is a limitation of the practical application of the current interrupted pacing and screwing technique.

      Left bundle branch pacing guided by premature ventricular complexes during implant.
      This study aimed to illustrate a novel implantation technique based on continuous pacing and monitoring of electrocardiograms and electrograms during lead screwing. The technique has the potential to make the procedure more effective, safer, and quicker.
