For as helpful as the Apple Watch is for keeping up with notifications and keeping tabs on your fitness, it's easy to forget that the increasingly popular wearable also has the ability to help save lives. This past Friday, James Green sent out a tweet explaining how the heart rate sensor on the Apple Watch did just that.
After receiving a notification that his heart rate was abnormally high, Green -- who was using the iOS app HeartWatch to monitor his heart rate readings from his Apple Watch -- went to the hospital to get things checked out. As it turns out, Green had a pulmonary embolism, a serious ailment that occurs when a blood clot is present in the lungs. Notably, a rapid or irregular heartbeat are just two of the few symptoms that often manifest when an individual has a pulmonary embolism.
