New ablation strategy aims to keep hearts in rhythm longer
NCT ID NCT02150902
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two catheter ablation techniques for atrial fibrillation (AF), a condition where the heart beats irregularly. One method uses a standard approach with a drug called adenosine to find missed spots, while the other adds an extra ring of ablation without the drug. Researchers want to see which method better prevents AF from coming back over 12 months. About 400 adults with paroxysmal AF are taking part across Canada.
