In Series 4 of the Apple Watch, the company added a new health feature. The electrocardiogram (ECG) monitors the user’s heart rhythm looking for an abnormal beat which could be the sign of Atrial fibrillation (AFib). The latter can lead to blood clots, a stroke, heart failure, and other heart-related complications. If there is no problem, your heart will show a normal sinus rhythm.
Included with the latest beta version of watchOS 7.2 just dropped by Apple, is the latest version of the algorithm created for the timepiece’s ECG monitoring system. This is titled “HKAppleECGAlgorithmVersion.version2” The “HK” stands for Health Kit and it is available on iOS 14.3 and Mac Catalyst 14.3.
