The update adds the ECG app to Watch Series 4 devices in the States (where the ECG is now only available) and also unlocks irregular heart rate warnings on all Apple Watch from Series 1 through to Series 4.

The Apple Watch Series 4 normally has a standard 14-day return period.

The ECG feature is created to "capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians", which could potentially save a lot of lives. This completes the circuit, measuring electrical signals across the heart. However, Series 1 and up will offer irregular heart rhythm notifications by checking your rhythm in the background and alerting you if signs of AFib are identified.

Now, it's rolling out as part of the watchOS 5.1.2 update. The ECG Watch app can then reveal any abnormal patterns, and the 30-second ECG can be presented to your doctor through a downloadable PDF. This means that the agency sees the ECG app as being of "low- to moderate-risk" to a user's health.

"We are confident in the ability of these features to help users have more informed conversations with their physicians", said Sumbul Desai, MD, Apple's vice president of Health. With the updated accelerometer in the Series 4, those Watches can now detect when its wearer has fallen, notifying loved ones and emergency services when the wearer cannot do so themselves.

Today, Apple released an ECG app for Apple Watch that allows users to perform a limited electrocardiogram test.

In that sub-study, of the participants that received an irregular rhythm notification on their Apple Watch while simultaneously wearing an ECG patch, 80 percent showed AFib on the ECG patch and 98 percent showed AFib or other clinically relevant arrhythmias.
You must have the Watch placed on its charger, connected to Wi-Fi or LTE, with at least 50-percent battery to download the update.
