The warning my wife received was a total false alarm, as we figured out now last Friday by a Cardiologist.
She is refusing now to use the AW anymore, as she was living in fear now for 8 weeks because of this false alarm.
I’m glad your wife is OK! Heart problems can be scary, but I hope someday she reconsiders her position.
A good friend of mine got an AFib warning after a run. He, a physician, mentioned it to his wife (also a physician), and she demanded that he get in the car to head to the emergency department. There they got his AFib under control and he’s doing well.
