New electric pulse method tested for stubborn heart rhythm disorder
NCT ID NCT06134752
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of ablation—pulse field and radiofrequency—for treating persistent atrial fibrillation, a common heart rhythm problem. Fifty participants will receive one of the two procedures to isolate faulty electrical areas in the heart. The goal is to see which method creates longer-lasting isolation and better controls abnormal heart rhythms over a year.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Pulse field ablation and radiofrequency ablation
- What this could lead to
- If pulse field ablation proves more durable, it could offer a more effective, safer option for controlling persistent atrial fibrillation.
- What could go wrong
- This is a small, early-stage comparison (50 participants) with no phase designation, so results may not be conclusive or widely applicable. Both procedures carry risks like bleeding or heart tissue damage.
