Key result
Apple Watch Irregular Rhythm Notification devices are increasingly used for atrial fibrillation management despite FDA clearance being limited to patients with no previous history of AF.
Why the study?
The Apple Watch Irregular Rhythm Notification feature is FDA cleared for individuals without prior AF, but is increasingly used for AF management.
Key points are not available for this paper at this time.
Design
Multi-center study
Potential mismatch between real-world use and FDA labeling warrants caution; leaves open the need for targeted validation studies.
The Apple Watch (AW) Irregular Rhythm Notification (IRN) feature uses photoplethysmography to identify prolonged episodes of irregular rhythm suggestive of atrial fibrillation (AF). IRN is FDA cleared for those with no previous history of AF, however, these devices are increasingly being used for AF management.
