The Apple Watch Series 4 comes with an ECG function that was recently released in the U.S. Since it became available for about a month, the feature is already proving to be a useful one. It was able to detect atrial fibrillation with the new feature and saved a man's life in Nashua, New Hampshire.
Barry Maden originally bought the Apple Watch to “keep a closer eye on his health after suffering a brain injury.” He bought the Apple Watch for it's Fall Detection feature. “He originally got it because they have a new fall risk app where, if he were to fall and I'm not nearby, the fall sensor will sense that he fell and call 911,” said his wife, Tara Maden.

He originally thought he was suffering from anxiety due to travelling for the holidays. However, his Apple Watch alerted him that his heart appeared to be in A-fib. It isn't clear if Maden used the ECG app right away to detect the A-fib. However, it was enough for him to double check if he was suffering from something serious. He soon thereafter took himself to the emergency room.
At the hospital, doctors performed their own tests using a more advanced ECG device to verify the Apple Watch's discovery. It was soon discovered that Maden's “heart was essentially stopped and restarted by doctors.”
The Apple Watch has been found to save lives previously and recently saved a woman from drowning in water as her car flipped over. You can read about all other instances where Apple Watch has been found detecting heart diseases here.
