Learning Curve and Initial Experience With Implementation of a His-Bundle Pacing Program in an Australian Setting

Abstract

Background: His-bundle pacing (HBP) has emerged as a promising technique to avoid pacing complications associated with dyssynchrony from right ventricular pacing, but data are limited to experienced operators and centres. We aimed to evaluate the implementation and outcomes of an HBP program in an Australian setting. Methods: Data were retrospectively collected on 140 consecutive HBP procedures attempted at three centres from March 2018 to September 2019. The cohort was divided into three groups (early: procedures 1–47, middle: 48–94, late: 95–140) to determine changes in procedural success in relation to operator experience. Results: Median age was 76 years (IQR 68–80 yrs); 69% were male. A..
