Introduction:
Physiological pacing offers the advantage of capturing His-purikinje system directly thereby achieving synchronized ventricular contraction1. Deshmukh et al2 first showed the feasibility of permanent his bundle pacing (HBP). Although HBP offers the most physiological form of pacing, it has some inherent limitations. Huang et al3 reported direct capture of left bundle (LB) by deep septal pacing as an alternative to overcome the limitations of HBP. Though the safety of LBBP has been established by several studies, the data for elderly population is lacking. This paper describes the feasibility, safety and electrophysiological properties of left bundle branch pacing in octogenarians.
