Ablation and pacing for patients with atrial fibrillation

Official title: Safety and Efficacy of Distal His Bundle Pacing Compared to Right Ventricular Pacing in Patients With Symptomatic Atrial Fibrillation Undergoing AV Node Ablation With Evidence of Heart Failure, a Randomised Control Study

Run by University Hospitals, Leicester · NCT06152406 · Data updated 2026-11-12

This study is testing whether a new type of heart pacing can help people with atrial fibrillation feel better compared to traditional pacing after they have a procedure to control their heart rhythm.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with symptomatic atrial fibrillation who are not suitable for rhythm control strategies and require AV node ablation.

Probably not a fit

Patients who already have a pacemaker or those with severe left ventricular systolic dysfunction may not benefit from this study.

What this trial studies

The Ablate and Pace HIS Study is a prospective randomized trial focusing on patients with symptomatic atrial fibrillation who are not suitable for rhythm control strategies. It aims to compare the outcomes of traditional right ventricular pacing against HIS bundle pacing in patients undergoing AV node ablation and pacemaker implantation. A total of 100 participants will be randomized into two groups, with endpoint measurements taken at multiple time points to assess the effectiveness of HIS pacing. The study is designed to be double-blinded to ensure unbiased results.

Why it matters

Potential benefit: If successful, this study could improve the quality of life for patients with atrial fibrillation by providing a more effective pacing strategy.

How similar studies have gone: Previous studies have shown promising results with HIS bundle pacing, indicating potential benefits over traditional pacing methods.
