For at least the second time, the Apple Watch is being credited with helping someone avoid sudden death because of heart problems. Following a report last September where a student athlete noted a very-high heart rate after football practice that saved him from what would have been a fatal attack of rhabdomyolysis, a Canadian builder has also been credited with saving his own life after noting a sky-high heart rate followed an undetected heart attack. The Alberta man, a watch collector, now says his other watches are put away, and the Apple Watch is his daily companion.
