|Experimental: Apple Heart Study App||
Device: Apple Heart Study App
The Apple Heart Study app is a mobile medical app that analyzes pulse rate data. The app identifies episodes of irregular heart rhythms consistent with atrial fibrillation and other arrhythmias.
- Atrial Fibrillation (AF) of greater than 30 seconds duration [ Time Frame: During ambulatory ECG monitoring (up to 8 days) ]Detected on ambulatory ECG monitoring for a participant who received an irregular pulse watch notification.
- Confirmed AF with a detection by a component of the app [ Time Frame: During ambulatory ECG monitoring (up to 8 days) ]Simultaneous ambulatory ECG monitoring indicating an irregular rhythm consistent with AF during time intervals when an app component is positive for an irregular pulse among those who received an irregular heartbeat notification.
- Concordant AF with app algorithm notification [ Time Frame: During ambulatory ECG monitoring (up to 8 days) ]Simultaneous ambulatory ECG monitoring indicating an irregular rhythm consistent with AF when the app based algorithm is positive for an irregular pulse among those who received a notification.
- Self-reported contact with a health care provider [ Time Frame: Up to 15 months ]Within 90 days following an irregular pulse watch notification
