Conditions obstructive sleep apnea, atrial fibrillation
Treatment implantable loop recorder insertion
Sponsor Queen's University
Collaborator Medtronic
Start date June 2011
End date July 2019
Trial size 31 participants
Trial identifier NCT01058551, Reveal XT-SA


Single site study: The goal of the study is to determine the incidence of new onset atrial fibrillation (AF) in patients with severe obstructive sleep apnea (OSA) syndrome through the use of a Medtronic Reveal XT implantable Loop recorder (ILR). The ILR device is approved for use in Canada, for the assessment of atrial fibrillation.

Primary Outcomes

To determine the incidence of new onset AF in patient's with severe OSA
time frame: 36 months

Secondary Outcomes

To determine the impact of continuous positive airway pressure (CPAP) treatment in patients with new onset of AF in patients with severe OSA. (post hoc analysis)
time frame: 36 months

Eligibility Criteria

Unable or unwilling to complete the study follow-up schedule (eg. intention to leave the Kingston area over the next 3 years. 8. Previously enrolled in this trial. 9. Enrolled in another study that would confound the results of this trial. 10. Documented history of heart failure 11. Diagnosed with severe obstructive sleep apnea greater than 1 year from screening date
