After a long wait, Apple Watch owners in Malaysia are now finally able to utilize the ECG app in their smartwatch today. This is due to the rollout of the new watchOS 7.5 and ADVERTISEMENT These updates have also opened up the irregular heart rhythm notification feature (IRNF) in Malaysia as well. IRNF is supported by all models across the family since Apple Watch Series 1 but you need either Apple Watch Series 4, Series 5, or Series 6 if you want to utilize the ECG app. Among the main aim of the ECG app and IRNF is allowing users to identify a heart condition called atrial fibrillation (AFib) which if left unchecked could lead to stroke. Dr Mohamed Ezani Taib of the National Heart Institute (IJN) pointed out that one-third of IJN’s 200,000 annual cases consist of AFib which showed how common this is in Malaysia.
