Key result
Right ventricular apical pacing was associated with a decreased mortality rate compared to right ventricular septal pacing following AVN ablation over up to 20 years of follow-up.
Why the study?
Does right ventricular septal pacing improve outcomes compared to right ventricular apical pacing in patients undergoing pacemaker implantation prior to AV node ablation?
Cohort (n=200)

No takes yet. Share an insight, caveat, or question.
RVA may be preferable post-AVN ablation in this cohort; leaves open whether randomized data would alter practice.
Eysenck et al. (2017) conducted a cohort in Atrioventricular node (AVN) ablation requiring pacemaker implantation (n=200). Right ventricular septal (RVS) pacing vs. Right ventricular apical (RVA) pacing was evaluated on Ejection fraction, dyssynchrony, and mortality rate. Right ventricular apical pacing was associated with a decreased mortality rate compared to right ventricular septal pacing following AVN ablation over up to 20 years of follow-up.
