ECG functionality will be enabled on the Apple Watch Series 4 in the publicly released version of watchOS 5.1.2, which is currently in beta testing, according to an internal Apple Store training document obtained by MacRumors.

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.

ECG and other heart data is collected in the Health app on a paired iPhone. Apple's document lists a minimum requirement of an iPhone 5s or later running iOS 12.1.1, currently in beta testing, or later.

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.

Apple's training document states that the ECG app is regulated and only available in regions cleared for use. The app will initially be limited to the United States, where Apple has received FDA clearance, but Apple Watch Series 4 models sold worldwide include the electrical heart sensor for future expansion.

Apple Store employees are instructed to advise customers that the ECG app is "not intended to be a diagnostic device or to replace traditional methods of diagnosis," and "should not be used to monitor or track disease state or change medication without first talking to a doctor," according to Apple's document.

Apple promised that the ECG app will be available later this year, but it's unclear when watchOS 5.1.2 and iOS 12.1.1 will be released. watchOS 5.1.2 has been in beta testing since November 7, while iOS 12.1.1 has been in beta testing since October 31, so both software updates should be released relatively soon.

A separate Apple training document obtained by MacRumors suggests that irregular heart rhythm notifications will also be enabled in watchOS 5.1.2 on Apple Watch Series 1 through Apple Watch Series 4 models.

The ECG app will not be available on previous-generation Apple Watch models, including the original through Series 3.

I am pissed that this will not work with my Series 3!! I could really use this app. Apple has a way to make me spend money. I might be stubborn and not buy a Series 4 until refurbs come along.

I’m betting we get it on monday, dec 3rd. Verizon announced eSim funtionality would be enabled early december which is waiting on the iOS 12.1.1 release, so it all kinda lines up.

hopefully this doesn't go the way of AirPower...and after thorough debugging, gets shipped.

The hardware is already in the watch, even those that people are currently wearing. It's not going in just to-be-sold watches. Anyone with a Series 4 will have this available.

So this will work in US but will it work in India where regulations on such devices are still not defined. I don’t want to change my Apple ID back to US.

You can buy a Kardiaband for you Series 3 if you really want this feature. From late 2017 until close to the announcement of the Series 4 Apple sold them in stores but took them out for obvious reasons (Apple wasn't actually the first to bring this function OTC and they didn't want people skipping on the 4)

Good idea. Health is a huge market and Apple is well positioned to control the wrist real estate. But, to succeed they need to make the Watch fully function with non-Apple phones and tablets.

Why would Apple do something so stupid? So that data whores hand round personal health data?
Privacy has never been an ambitious goal for Android and MS. They dance at other parties.

No wonder that in the EU Android could not reach a sufficient level for certified health care.

No they don't. This is very sensitive health data, and it's not Apple's job to facilitate building a doorway for a bunch of hackneyed Android devs to screw it up and cause problems. Then Apple will be blamed for Google's failure to properly secure their platform. That's to say NOTHING of insurers, who would love to "better serve you" by accessing that and deciding how quickly they want to lobby you off their roster.
