This Apple Watch detected a heart attack early
The Apple Watch comes with a lot of handy features but this one might actually save your life by sensing an impending heart attack
The Apple Watch relays notifications from your phone and lets you communicate in new and interesting ways, but it could also save your life.
That's because it passively monitors your heart rate using light sensors on the underside, and keeping an eye on it could be the first step in getting to the hospital in time. That's what happened when Canadian builder Dennis Anselmo was working on setting up fencing posts in August 2015. Via cultofmac, the 62 year old checked his heart rate on his new Apple Watch and noted it was much higher than usual - 210 beats per minute rather than 50.
Someone dialled 999 immediately and the ambulance arrived quickly, whisking him away to hospital. When he arrived: "They told me that if I had gone home and gone to bed - as many people do - I would likely have had another, more serious bout in the middle of the night. Those second attacks are the ones that kill. That is a common problem."
The lesson here is clear - if you notice something unusual in any kind of person heart rate monitoring, it's best to get yourself checked by a professional as soon as possible.
