First seen Feb 13, 2026 · Last updated May 16, 2026 · Updated 13 times

Summary

This study looks at 60 adults who already have a special pacemaker and recently had a heart ablation for rapid atrial fibrillation. Researchers want to see if pacing the heart's natural electrical system (left bundle branch) helps people exercise better compared to standard right ventricular pacing. The main measure is how much oxygen they use during peak exercise.
