According to James Green from Brooklyn, NY, his Apple Watch was able to alert him to an elevated heart rate which was the start of a pulmonary embolism. Green was able to seek medical care before his condition escalated, WCCFTech reports.

James Green had a pulmonary embolism a few years before he bought the Apple Watch. However, the quick access to reading his heart rate definitely proved worthwhile for Green. In a statement Green noted:“It was cool to open up the Health app and show it to my physicians and give them more data to work with. I had no idea this watch would save my life.”
