This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Atrial fibrillation is a common irregular heartbeat that often comes back after a procedure called catheter ablation, even when the surgery is successful. Sleep apnea — a condition where breathing stops during sleep — makes this relapse more likely. This trial tests whether using a breathing machine called CPAP for 12 months after ablation can prevent the irregular heartbeat from returning, compared to standard care alone.
Up to 45% of patients have their irregular heartbeat return within a year after ablation, and sleep apnea is a major reason why. Doctors know the breathing machine can help sleep apnea, but they don't yet know if treating sleep apnea this way also keeps the heart rhythm stable after surgery.

You will be randomly assigned to either use a CPAP breathing machine every night for 12 months plus receive standard heart care, or to receive standard heart care alone. Both groups will have heart rhythm monitoring and check-ins at 1, 3, 6, and 12 months to see if your irregular heartbeat returns. The study will track how often you use the breathing machine and monitor your overall health and quality of life throughout the year.
