Irregular rhythm notifications.
The irregular rhythm notification occasionally checks for signs of irregular rhythms that may be suggestive of atrial fibrillation (AFib). This feature won’t detect all instances of AFib but may catch something that can provide your patients with an early indication that further evaluation may be warranted.
Irregular rhythm notifications use the optical heart sensor to detect the pulse wave at the wrist and look for variability in beat‑to‑beat intervals when the user is at rest. If the algorithm repeatedly detects an irregular rhythm suggestive of AFib, your patient will receive a notification and the date, time, and beat‑to‑beat heart rate will be recorded in the Health app.
The irregular rhythm notification feature has been granted De Novo classification by the FDA for users 22 years and older in the U.S. with no prior history of AFib.
