Deepthy Varghese, MSN, ACNP, FNP, is joined by guests Martha G. Ferrara, DNP, FNP, FHRS, CCDS, and Dinesh Sharma, MD, MPH, FHRS, for a discussion of the accuracy of the Apple Watch for detection of AF. 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. The objective of the present study was to determine the accuracy of the IRN in subjects with a previous diagnosis of nonpermanent AF. In a population with known AF, the AW IRN had a low rate of false positive detections and high specificity. Sensitivity for detection by subject and by AF episode was lower. The current IRN algorithm appears accurate for AF screening as currently cleared, but increased sensitivity and wear times would be necessary for disease management.
