Summary

This study tests whether a newer pacing method (conduction system pacing) is as good as or better than standard biventricular pacing in heart failure patients with atrial fibrillation who need a heart ablation. About 82 participants will be randomly assigned to one of the two pacing types. The main goal is to see how well the heart pumps blood after treatment.

What this could mean

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

Active substance: pacemaker implantation (biventricular or conduction system pacing)
What this could lead to: If successful, this could show that conduction system pacing is a better option than standard biventricular pacing for managing heart failure after ablation.
What could go wrong: This is a mid-sized trial (82 participants) and results may not apply to all patients. The study is not yet recruiting, so outcomes are uncertain.
