Apple has designed a new algorithm that Apple Watch uses to measure electrocardiogram (ECG) waves, according to developer documentation for the iOS 14.3 and watchOS 7.2 betas.
In the official documentation, a new "version 2 algorithm" declaration has been added. No other information is included.
The ECG feature includes irregular heart rhythm detection, which intermittently measures the user's heart rate in the background and sends a notification if it detects an anomaly it categorizes as atrial fibrillation, which can be a serious heart arrhythmia condition.
Based on beta code uncovered by MacRumors, it's likely that the new algorithm will allow the ECG app to check for atrial fibrillation (AFib) at higher heart rates - during exercise, for example.
iOS 14.3 will introduce support for 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. VO2Max is a useful measurement of overall fitness and heart health.
iOS 14.3 is set to be released on Monday, December 14, which is also the day that Apple Fitness+ is coming out.
Apple's watchOS 27, previewed at this month's WWDC, removes four built-in apps from all supported Apple Watch models, folding three of them into a single Find My app and dropping Walkie-Talkie entirely, based on the first developer beta released this month.
The largest change affects Find My. watchOS 27 developer beta 1 replaces the separate Find Devices, Find People, and Find Items apps...
Apple today shared a video showing off the Apple Watch in use at the World Surf League Championship Tour, with surfers describing how they use the watch when competing.
Surfers can be hundreds of meters away from the beach during competitions and can't hear announcements over the sound of the water and the wind. The World Surf League has adopted the Apple Watch to solve the problem, linking...
A "major overhaul" of the Apple Watch's design is due to arrive next year with a new system for connecting bands, according to a known Weibo leaker.
In a set of recent posts, the leaker known as "Instant Digital" linked the new claim to older rumors about an "Apple Watch X" model, which was said to introduce a fresh design and break compatibility with the existing watch band system. Citing...
Wait what? The ECG only works when your finger is on the Digital Crown. It can’t work in the background.
The background irregular heart rhythm detection does not use the ECG but it is grouped with the ECG features (which is technically inaccurate but they are related features, just different technologies). It's been around as long as the ECG: "Using the optical heart sensor in Apple Watch Series 1 or later, the irregular rhythm notification feature will occasionally check the user’s heart rhythm in the background for signs of an irregular heart rhythm that appears to be AFib and alerts the user with a notification if an irregular rhythm is detected on five rhythm checks over a minimum of 65 minutes."

Still waiting for ECG in Japan! Any news about it?
Since ECG received final medical approval in Japan this September, I guess maybe iOS 14.3 will cover ECG functionality also Japan as well? *finger-crossed*
