The PPG-based feature automatically measures the wearer's heart rhythm every five minutes, and will be ready for integration with a range of devices later this year.

An algorithm trained on a deep neural network was able to perform on par with board certified cardiologist when annotating 12 different types of heart rhythms.
In addition, Apple shared some snippets of the validation data it shared with the FDA.
The app monitors heart rhythms via the smartphone's camera and uses AI to identify irregularities.
AI company physIQ landed FDA clearence for its atrial fibrillation detection analytics software.
