Conduction system pacing associated with reduced heart failure hospitalizations and all-cause mortality compared with traditional right ventricular pacing in the Medicare population

Heart RhythmPublished Retrospective cohort study

Authors' conclusion

DC pacemaker patients treated with CSP using a 3830 catheter-delivered lead experienced significant all-cause mortality and heart failure hospitalization benefits compared with DC RV pacing. LBBAP had lower complications compared with HBP.
