The Apple Watch saved the life of a 29-year-old woman from Cincinnati by detecting a pulmonary embolism in her sleep. The watch measures heart rate throughout the day and detects high or abnormal heart rates while resting. It uses photoplethysmography technology to measure heart rate. Heart rate monitoring can be enabled by going to the "Settings" application on the watch or the Apple Watch app on the iPhone.
