This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Atrial fibrillation is an irregular heart rhythm that affects millions of people. This trial is testing whether personalizing ablation treatment—a procedure that uses heat or cold to fix the irregular areas in your heart—based on your individual heart's electrical properties can help keep your heart rhythm normal longer. The study will map your heart tissue during the procedure to guide exactly where treatment is needed.
Current ablation treatment works well for some patients but not everyone. Doctors want to understand whether customizing the treatment based on each person's unique heart tissue patterns—rather than using the same approach for everyone—can improve how well the treatment works and prevent the irregular rhythm from coming back.

You will undergo a catheter ablation procedure at Barts Heart Centre, where doctors will create an electrical map of your heart to identify abnormal tissue patterns. Depending on what they find, you may be part of one of several studies testing different approaches to treating those patterns. After your procedure, you will be followed for 12 months with visits to check whether your heart rhythm has remained normal and to monitor for any complications.
