Sleep Study Using Polygraphy in Adults with Paroxysmal Atrial Fibrillation Undergoing Pulmonary Vein Isolation Ablation

What this Trial Is About

Researchers are studying sleep patterns in people with paroxysmal atrial fibrillation who are scheduled for pulmonary vein isolation, a procedure to control heart rhythm. The study aims to see how sleep parameters, especially the apnea-hypopnea index AHI, change during treatment. This observational study uses polygraphy to monitor sleep without affecting patients regular care. Participants will undergo four sleep studies using polygraphy to record pulse oximetry, heart rate, chest and abdominal movements, and nasal airflow. Two studies occur before the ablation procedure, spaced at least 7 days apart, and two after the procedure, starting one month later, also spaced by at least 7 days. The ablation itself is a routine clinical procedure and not part of the study. During the study, participants will receive standard care including lifestyle advice and therapies as needed. Researchers will track sleep parameters before and after ablation using certified sleep-monitoring devices. The main outcome is the change in AHI from baseline over about one year. Participation involves non-invasive sleep monitoring and does not interfere with usual treatment, with data protected according to privacy regulations.
