Which pacemaker setting helps heart patients breathe easier?

NCT ID NCT06061978

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

Summary

This study looks at 60 adults with rapid atrial fibrillation who already have a pacemaker and recently had a heart ablation procedure. Researchers want to see if pacing the heart's natural electrical system (left bundle branch) helps patients exercise better compared to standard right ventricular pacing. The main goal is to measure maximum oxygen use during exercise, which reflects heart and lung fitness.
