Pacemaker vs. pills: which works better for irregular heartbeat and heart failure?

NCT ID NCT06299514

First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

This study tests whether a pacemaker plus a heart ablation procedure is better than standard medications for controlling heart rate in 600 people with both atrial fibrillation and heart failure. Participants will either get a pacemaker implant and ablation, or continue with optimized heart failure drugs. The goal is to see which approach reduces deaths, heart failure events, and improves quality of life.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Pacemaker and ablation procedure (conduction system pacing with AV node ablation) versus standard heart failure medications

What this could lead to

If successful, this could show that a pacemaker plus ablation is a better option than medication for controlling heart rate and improving quality of life in people with atrial fibrillation and heart failure.

What could go wrong

This is a large trial, but it is not yet complete. The pacemaker procedure carries risks like infection or bleeding, and it may not prove to be better than medication for everyone.
