For the present project the investigators have established a research team from 2 different university hospitals. This team, including high ranked, internationally renowned scientist from both clinical and basic sciences, will make a framework for PhD candidates and will ensure the patient cohort. Patients with paroxysmal AF and SA will be examined with an extensive diagnostic battery including advanced cardiac imaging tools allowing a proper description of the heart. Then a Reveal that continuously monitor the rhythm of the heart will be inserted, allowing the influence of SA, physical activity, inflammatory parameters, and other external variables on total AF burden to be examined. The patients will then be randomized to treatment of SA with a CPAP or not, and the AF burden recorded 6 months before ablation and 6 months after. The present investigations carried out, are expected to results in better understanding of the interaction between AF and SA and may lay the scientific basis for better diagnostic and therapeutic approaches for patients with AF. In addition, given the advantage of continuous Reveal® recording of the patient's heart rhythm, the present study will examine possible triggers of AF such as activity level and inflammatory substances, and examine the role of structural abnormalities in the heart as assessed by echocardiography for the triggering of AF episodes. An overall aim is therefore a better phenotyping of the patient which could aid in a more person-specific treatment approach, with direct consequences both for the individual patient and for the society.
