In April 2018 Apple called one morning to tell me my watch had detected a rapid heart beat during the night while I was sleeping. They asked me to wear a heart monitor, free, for two weeks for their research. I agreed, and they later sent report to my doctor, who confirmed I have atrial fibrillation, A-fib. I now have a pacemaker and take appropriate meds. Feel lucky to have turned 91st recently. Needless to say, I love my Apple watch.
