Heart rate sensors aren’t exactly new and we’ve seen them make their debut in fitness trackers in the past, where previously they would exist as separate standalone accessories. However, with the Apple Watch, heart rate sensors have evolved to be more than just a way to measure heart rate, and we have heard numerous stories of how the feature has saved many lives by alerting them to a higher than normal heart rate.

Such was the case where Roy Robinson, a 74-year old man, was saved by his Apple Watch when it alerted him to a possible A-Fib, thanks to the ECG monitoring tool built into the watch. The best part was that Robinson had no idea what an A-Fib was to begin with, but when he was alerted, his son pushed him to go to the emergency room where he was later admitted.

It is unclear as to what could have caused the A-Fib alert to go off on Robinson’s watch as it was not detailed. Robinson was also unsure if the Apple Watch saved his life, but he believes that it definitely played a role. In such cases, being alerted to a problem early is what helps lives being said.

For example, had his watch not constantly alerted him to a possible A-Fib, Robinson could have just simply gone home to rest where it might have been too late. Robinson also pointed out that the best part of the entire ordeal was when Apple’s CEO Tim Cook sent him a personal email.
