This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are studying blood markers — substances in your blood that may predict whether your atrial fibrillation will come back after treatment. You'll have blood samples taken before and after your scheduled ablation procedure (a catheter treatment) or electrical cardioversion (a shock treatment to restore normal rhythm), and researchers will look for patterns that help predict who is at higher risk of the condition returning.
After heart rhythm treatment, some patients' atrial fibrillation returns while others stay in normal rhythm. Doctors don't currently have a reliable way to predict who will relapse, so this study is looking for blood-based clues that could help identify at-risk patients early and guide better follow-up care.

You will have blood drawn the day before and the day after your ablation or cardioversion procedure. After your treatment, you'll wear a heart rhythm monitor for two weeks (starting three months after the procedure) to check for any irregular heartbeats. You'll then have follow-up clinic visits at 4 months, 8 months, 12 months, and 24 months to assess whether your atrial fibrillation has returned.
