A look at the Apple Watch’s ECG, from someone who needs it

When Apple introduced the fourth iteration of its smartwatch, the big new selling point wasn't a feature we typically associate with a watch or any sort of smart device. Instead, the company added a feature that had only recently arrived in the form of specialized consumer devices: an electrocardiograph (ECG), a device made for monitoring the heart's electrical activity.

But the watch was ready before the software was, meaning an examination of the technology wasn't possible in our comprehensive review of the Apple Watch Series 4. Last week, Apple finally enabled the missing features, and we've spent a few days checking them out.

Basic features

People who haven't used the Apple Watch may not realize just how much it's an extension of an iPhone. This includes the heart-monitoring software, which requires an update to both the Watch and iPhone OSes before it will work. (This caused a small bit of confusion when the software wouldn't launch after we upgraded only the watch's OS.) Once the update is done, the Health app on the iPhone will incorporate any ECG data generated using the watch. On the watch side, the update will install a new app.

The newest update for Apple Watches is out now, bringing a highly anticipated feature to Series 4 devices. Apple pushed out watchOS 5.1.2 today, which includes its ECG app for monitoring irregular heartbeats.

Apple Watch Series 4 devices all have built-in electrodes that can measure electrocardiograms, or ECGs. At the time of the Watch's debut in September, Apple's native app with which the electrodes communicate wasn't ready for consumer use. Now, it's rolling out as part of the watchOS 5.1.2 update.

The ECG app is for the Watch itself, while ECG data gets stored in Apple's Health app on iOS devices. To take an ECG reading, users must place their finger on the flat side of the Digital Crown on their Series 4 Watch. The electrode on the Digital Crown communicates with the other electrode on the Watch, which sits near the heart rate monitor, to take a complete ECG measurement.
