Dr. Ray Emerson received a notification from his Apple Watch saying that it had noticed an irregular heartbeat, CBS Austin reported recently.
As per report, Dr. Emerson joked that he was "too cheap" to buy the watch for himself, but now he views his Apple Watch as priceless.
There have been several examples where Apple Watch saved lives.
A US doctor recently saved a person's life by using Apple Watch Series 4 on his wrist to detect atrial fibrillation (AFib) at a restaurant.
An Apple Watch user in the UK was recently alerted about his low heart rate by the device. It revealed a serious heart condition that ultimately resulted in a surgery to fix the problem.
