When I get AFib, I feel bad and can by just checking my pulse from the wrist determine if I have an AFib.
With the Apple watch I can verify how bad it is, should I just wait if it go away or should I go to hospital.
I have been "re-booted" several times, once with some medicine and that was scary, you are awake and feel that your heart slowly stop. Normally they put you to sleep and start with electricity, that's what they told me.
I see no reason to monitor my ECG constantly, the only problem I have now is that when I need the watch to what is going on, it's dead.
There are so many series of Apple watch and different OS, some wrote that with the new series watch, Apple decided that users can not actually shut the watch down. I have no idea it this is true or not, but as my watch is usually dead, I think it's true? Mine is series 9.
