watchOS 5.1.2 will be publicly released today and will enable the long-awaited ECG app on Apple Watch Series 4 models in the United States, according to a report by The Verge. The article has since been pulled, however, possibly because the information was under embargo and published at the incorrect hour.

If the report proves to be accurate, the software update should be available through the Apple Watch app on iPhone around 10:00 a.m. Pacific Time as usual.

Last week, MacRumors was first to report that watchOS 5.1.2 will enable the ECG app on Apple Watch Series 4 models, based on an internal Apple Store training document. ECG data will be available in the Health app on an iPhone 5s or newer after updating to iOS 12.1.1, released to the public yesterday.

watchOS 5.1.2 will feature an Apple-designed ECG app that can indicate whether your heart rhythm shows signs of atrial fibrillation, a serious form of irregular heart rhythm, or a normal sinus rhythm. Apple Watch Series 4 is capable of generating an ECG similar to a single-lead electrocardiogram, according to the FDA.

To take an ECG reading from the Apple Watch, users will need to place a finger on the Digital Crown while wearing the watch. The reading is completed in 30 seconds, allowing users to determine whether their hearts are beating in a regular pattern or if there are signs of atrial fibrillation.
