His Bundle Pacing in the Era of Left Bundle Branch Pacing.

Abstract

Soon after the rapid growth of the popularity of His bundle pacing (HBP), the use of this conduction system pacing modality was overshadowed by left bundle branch area pacing (LBBAP). This focused review on HBP addresses whether there are any advantages of HBP over LBBAP and what the current uses of HBP may be. We conclude that HBP must be considered as an alternative physiological pacing method with several potential applications, undoubtedly at least as a rescue option for failed CRT/LBBAP. For wider application of HBP, prospective studies are needed to document a reduction in the incidence of late threshold rise with modern implantation techniques. Nevertheless, HBP should be available in every modern pacing laboratory. This requires an active HBP program to maintain and develop the ability of operators to deliver HBP when it is most needed.
