This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is investigating why women and men respond differently to a common heart rhythm procedure called pulmonary vein isolation (PVI ablation). Researchers will map the heart's electrical activity in detail during your ablation procedure to look for hidden abnormal sites that standard treatment may miss. The goal is to understand whether these unmapped areas explain why women have lower success rates with this procedure.
Women consistently have worse long-term outcomes after standard heart rhythm ablation compared to men, but doctors don't fully understand why. This study tests whether women have more hidden abnormal electrical sites in the heart that aren't caught by standard treatment, which could explain the difference in outcomes.

You will undergo your standard ablation procedure as planned. During the procedure, your doctors will perform detailed electrical mapping of your heart to identify any abnormal sites beyond the standard treatment areas—these sites will be documented but not treated during this first procedure. After your ablation, you will have intensive follow-up appointments over 1 year to track whether your heart rhythm remains stable and to see if untreated abnormal sites lead to recurrence of your irregular heartbeat.
