NCT ID NCT07645066

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether pacing the heart from a specific spot (posterosuperior bundle) can lower the chance of atrial fibrillation (AF) in people with sinus node dysfunction (a slow or irregular heartbeat). About 300 adults who need a pacemaker will be randomly assigned to get pacing from the new spot or the standard spot. Researchers will track AF episodes lasting 6 minutes or longer for up to 2 years.
