His Bundle (Conduction System) Pacing: A Contemporary Appraisal

: The His bundle (conduction system) is an attractive target for physiologic pacing because it uses the native conduction system. Although the potential benefits of conduction system pacing were recognized in the 1970s, in the past 2 decades, it has grown in interest as a potentially preferred method of ventricular stimulation in appropriate patients. This review provides an appraisal of conduction system pacing, with focus on anatomy, physiology, tools, and techniques as well as an appraisal of current published data and thoughts on future directions.
