Following Apple's introduction of ECG function to Europe and Hong Kong, China, in the watchOS 5.2 update in March this year, another country is about to join Apple's Watch Series 4 ECG support ranks, namely Canada.
According to the latest news today, in the Canadian Ministry of Health database, Apple has obtained permission for ECG function on Apple Watch Series 4, and the ECG irregular heart rate rhythm notification shows approval on May 16. This means that ECG features will soon be available in Canada, perhaps when iOS 12.4 and watchOS 5.3 are officially launched.
From multiple sources, we can be sure that each Apple Watch Series 4 has built-in ECG hardware, but software access is prohibited. If you want to launch ECG in a country or region, you must get permission from the local health and medical authorities. As early as December 2018, watchOS 5.1.3 introduced ECG functions, but the application area is limited to the United States, Puerto Rico, the United States Virgin Islands and Guam. Subsequently, in watchOS 5.2, ECG landed in 19 European countries and Hong Kong, China.
Although there is no news to support the state-owned version of ECG, some of you have experienced the Hong Kong version of ECG. Apple Watch Series 4 (US version, Hong Kong version or some European version) and the SIM card of Hong Kong operators can be activated, and the ECG application does not seem to disappear after changing the card.
ECG has attracted much attention as the highlight of Apple Watch Series 4, which is used to measure heart activity, detect abnormal rhythms and diagnose heart conditions. Apple Watch sends notifications to users when it detects irregular rhythms. It's very simple to get ECG data, just wear Apple Watch, start the test, and put your finger on the digital crown for 30 seconds. After the ECG readings are obtained, the system provides a heart rate chart, which users can share with doctors.
