Yesterday, Apple quietly updated the beta version of WatchOS 8.3 beta 4. A seemingly ordinary small update contains a major update, which is an important function that many watch users have been looking forward to for many years.
Some netizens found that this version has actually opened the ECG function of ECG, and the ECG function of ECG that has been waiting for many years has finally arrived.
According to the introduction of ECG function in Apple Health App, you can do ECG on Apple Watch after opening this service. "ECG App uses the digital crown of Apple Watch to record the heartbeat, and then the App will check whether there are forms of atrial fibrillation and arrhythmia.
Actually, this is not the first time. As early as 20 18, the function of ECG detection was introduced on Apple Watch 4. However, because this function belongs to the nature of medical devices, Apple failed to pass the medical device certification of the Food and Drug Administration, so it cannot be used in China.
At present, this function has been used by users in the beta version. Relevant settings can be found in Heart Health, and can be upgraded if necessary.
Although it is a beta version, note that this is an RC version, which is equivalent to a semi-official version. If you are not in a hurry, you can wait. If there are no problems, the official version will be online soon.
