This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a newer ablation technique called pulsed field ablation works better than the standard radiofrequency ablation method for treating recurring atrial fibrillation (irregular heartbeat) in patients who have already had one ablation procedure. Both methods use a catheter—a thin tube inserted through blood vessels to the heart—to fix the problem areas causing the irregular rhythm. The study will help doctors understand which approach is more effective for patients whose condition has come back.
Many patients whose irregular heartbeat was initially treated with ablation experience a return of symptoms, requiring a second procedure. This trial exists to determine whether the newer pulsed field ablation technique offers better, longer-lasting results than the traditional radiofrequency method for these repeat cases.

If you enroll, you will first have a small monitoring device implanted under your skin about one month before the ablation procedure to track your heart rhythm. On the procedure day, you will be randomly assigned to receive either pulsed field ablation or radiofrequency ablation. During the procedure, doctors will use a catheter to access your heart and treat the areas causing irregular heartbeats. After the procedure, you will have regular follow-up visits to check your heart rhythm and ensure the treatment is working well.
