In addition to releasing iOS 13, Apple on Thursday also rolled out the watchOS 6 update to select Apple Watch models. Apart from new apps like Noise and Voice Memos as well as features such as menstrual cycle tracking and the ability to install apps directly from the watch itself, the update brings new health-focussed features to India. First is notifications for irregular heart rhythm (A-fib detection), which will be available to all Apple Watch models that receive the watch OS 6 update. Additionally, Apple Watch Series 4 users will now be able to record electrocardiograms using the built-in ECG app. The features will also be available in Apple Watch Series 5 when it goes on sale in the country next week.
Atrial fibrillation, or A-fib, is an abnormal heart rhythm, which indicates rapid and irregular beating of the heart. Sometimes, it’s accompanied by other symptoms like chest pain, but quite often, there are no outwards signs. If left untreated, A-fib can result in stroke, which makes timely detection of A-fib extremely important.
The irregular rhythm notification feature can occasionally check heart rhythms in the background and send a notification if an irregular heart rhythm that appears to be atrial fibrillation (A-fib) is identified. Apple notes that the Apple Watch is not constantly looking for A-fib, so all instances of A-fib may not be detected.
