iOS 14.3 and watchOS 7.2 Include New Apple Watch ECG Algorithm Version

The latest betas of Apple’s iOS 14.3 and watchOS 7.2 include a new algorithm for use by the Apple Watch to measure electrocardiogram (ECG) waves.

The information is included in the developer documentation for iOS 14.3 and watchOS 7.2. (Shared by¬†MacRumors) In the documentation, a new “version 2 algorithm” declaration has been added. No other information is included.

The ECG feature debuted alongside the Apple Watch Series 4 and offers users the ability to check for signs of atrial fibrillation or sinus rhythm.

Based on the beta code uncovered by MacRumors, it looks as if that the new algorithm will allow the ECG app to check for atrial fibrillation (AFib) at higher heart rates – during exercise, for example.

The new algorithm will debut alongside Apple Fitness+, Apple’s upcoming fitness service that will work with the Apple Watch, plus it brings a new Cardio Fitness feature that lets you know if your VO2Max levels are low.

iOS 14.3 is expected to be released on Monday, December 14, which is also the day that Apple Fitness+ debuts.
