First seen Jan 30, 2026 · Last updated May 21, 2026 · Updated 14 times
Summary
This study looks at 70 people with heart failure, atrial fibrillation (an irregular heartbeat), and a special pacemaker (CRT) that isn't working as well as it should. Participants will be randomly assigned to one of two procedures: ablation of the faulty electrical signals in the heart's upper chambers, or ablation of the signal pathway between the upper and lower chambers. The goal is to see which approach better improves heart function and quality of life over 6 months.
