Videos show how Apple Watch saves lives; new update to watchOS 5.1.2 could save more

The second video focuses on a young man named Michael Jackson (no, not that Michael Jackson) who has spastic quadriplegic cerebral palsy. A notification from his Apple Watch about his heart rate sent him to the ER where it was determined that he had sepsis. And once again, early warning from the timepiece was able to save another life.

In a related note, Apple today released watchOS 5.1.2. The update activates the ECG feature found on the Series 4 version of the watch, which will look for abnormal heart rhythms. New complications that come with the update include Mail, Messages, Home, Maps, Apple News, Find My Friends, Phone, and Remote. To update your watch, go to the Apple Watch app on your iPhone and go to General > Software Update. The battery on the Apple Watch must be charged to at least 50% and the device itself must be on the charger, and within close range to the iPhone.
