It definitely is if you’re over 55. A quick story… Three weeks ago I was sitting on my couch watching TV and my Apple 5 watch went off with an afib alert. I’m 69, I’ve never had a problem with my heart in my life, I in good shape, not overweight, and ran marathons 15 years ago and still run today. I thought it was a fluke. I waited a day and then read that afib causes stroke more than it does heart attack, so I went to the ER. Sure enough, I had a strong case of afib with a heart rate would not come down less than 105… Two days later they did an electrical stimulation to put the heart back in normal rhythm and I’ve been fine ever since. The real key is I had absolutely no symptoms at all, had no idea that I was in a fib. It’s my opinion that the watch saved me.
