Popis: Abstract Background The Mt FUJI study was a multicenter, prospective, randomized, single‐blind, controlled trial comparing delivery catheter‐based and stylet‐based right ventricular (RV) lead placement at the RV septum. This study extended the follow‐up duration to 1 year after implantation. Methods Seventy patients with pacemaker indications for atrioventricular block were randomly assigned to the delivery catheter and stylet groups. We compared the mid‐term efficacy and safety between the two groups at 1 year after implantation. The primary outcome was the change in the left ventricular ejection fraction (LVEF), and the secondary outcomes were changes in brain natriuretic peptide (BNP) levels, lead parameters, paced QRS duration, and the incidence of adverse events. Results At the 1‐year follow‐up, no significant differences were observed in the changes in the LVEF (+1.0% ± 8.6% vs. +3.1% ± 8.1%, p = .332), BNP levels (+8.0 [−11.1, 26.5] pg/mL vs. −8.7 [−15.3, 13.2] pg/mL, p = .193), or lead performance between the delivery catheter and stylet groups. The QRS duration was significantly shorter in the delivery catheter group than in the stylet group (128 ± 23 ms vs. 146 ± 17 ms, p
