Posterosuperior Bundle Pacing for Prevention of Atrial Fibrillation in Patients With Sinus Node Dysfunction (PSB-AF)
3. August 2026 aktualisiert von: Shanghai Tong Ren Hospital
A Prospective, Multicenter, Randomized Controlled Trial Evaluating the Effect of Posterosuperior Bundle Pacing on Atrial Fibrillation Prevention in Patients With Sinus Node Dysfunction
This study aims to evaluate whether posterosuperior bundle (PSB) pacing reduces the incidence of atrial fibrillation (AF) in patients with sinus node dysfunction (SND) undergoing pacemaker implantation.
Approximately 300 patients will be enrolled and randomized to receive atrial pacing at either the PSB region or the right atrial appendage (RAA).
The primary endpoint is the occurrence of AF episodes lasting ≥6 minutes, as detected by device or surface electrocardiogram.
Patients will be followed for up to 24 months.

Detaillierte Beschreibung
Sinus node dysfunction (SND) is a common indication for permanent pacemaker implantation.
Conventional right atrial appendage (RAA) pacing may result in delayed or dyssynchronous atrial activation, potentially increasing the risk of atrial arrhythmias.
Posterosuperior bundle (PSB) pacing is a novel physiological atrial pacing approach.
This study is a prospective, multicenter, open-label, randomized controlled trial.
A total of approximately 300 eligible SND patients indicated for pacemaker implantation will be enrolled and randomly assigned (1:1) to PSB pacing or RAA pacing.
Ventricular pacing will be performed using left bundle branch area pacing in both groups.
Participants will be followed at 3, 6, 12, and 24 months after implantation.
The primary endpoint is the occurrence of AF episodes lasting ≥6 minutes.
Secondary endpoints include atrial high-rate episodes, AF burden, pacing parameters, ECG and echocardiographic indices, laboratory findings, and mortality outcomes.
Safety endpoints include procedural complications and device-related adverse events.
