Żyrardowska 31, 05-825 Grodzisk Mazowiecki, Poland NIP (Tax ID): 529 183 03 11 Dear Sir/Madam, You have been invited to participate in a scientific study aimed at assessing sleep parameters in patients with atrial fibrillation undergoing rhythm-control therapy. Please read this document carefully before deciding whether to take part in the study. If you have any questions, please contact the principal investigator. Study Objective: To assess sleep parameters using polygraphy in the course of treatment of patients with paroxysmal atrial fibrillation qualified for pulmonary vein isolation. Study Procedures: The study involves four polygraphic sleep studies (two before and two after atrial fibrillation ablation), each conducted at least 7 days apart. The polygraphic studies will record the following parameters: pulse oximetry, heart rate, respiratory movements of the chest, and airflow through the anterior nares. The study includes only patients undergoing atrial fibrillation ablation for the first time. Risks and Benefits: The study is non-invasive and does not involve any direct health risks. Participation will not affect your treatment process, but it may provide valuable information about your health status. Voluntary Participation: Participation in the study is entirely voluntary.
