It can capture heart rhythm on demand in a moment when users experience symptoms such as a rapid or skipped a heartbeat and help provide clinically important data to physicians. The irregular rhythm notification feature on Apple Watch occasionally checks heart rhythm in the background and sends a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.

The ECG app and irregular rhythm notification feature can alert users to signs of AFib. “We’ve seen the ECG app and irregular rhythm notifications on Apple Watch have a meaningful impact on our customers across the US,” said Jeff Williams, Apple’s Chief Operating Officer.
A recent clinical trial of around 600 participants found that the ECG app on Apple Watch demonstrated 98.3 percent sensitivity in classifying AFib and 99.6 percent specificity in classifying sinus rhythm in classifiable recordings, when compared to an ECG administered by a cardiologist.
The irregular rhythm notification feature was recently studied in the Apple Heart Study which found “only 0.5 percent of participants received irregular pulse notifications, an important finding given concerns about potential over-notification.”
