last Night when I was just laying down watching TV, my galaxy watch 42mm read my heart rate to be 220 bpm. 10 minutes later it was 90bpm. I really freaked out and went to the hospital to measure my heart rate again , in the hospital the heart rate was normal, 80 bpm. I was relieved but still concerned about the 220 bpm.

Both incidents were reported from 10-11PM when I was laying down doing nothing!
