Any armchair medics about?

[Possiblymaybeish]

I never thought I'd be posting one of these threads but I don't know if there is something wrong with me I've made a GP appointment but would anyone like to diagnose me in the waiting room (it's a long wait) I apparently had a strange breathing episode one evening I felt fine but my DH said I was breathing strangely whilst lying down watching to. The heart rate monitor on my watch said it was very high. Since then I seem to have a slightly higher heart rate in general, it drops a lot when I stand up or go upstairs and seems to go high until it settles back. I don't have any new symptoms and feel a bit stupid saying I think my watch thinks I have something wrong! Pic is my heartrate from that day

Other examples one from a day before the odd moment and one more recently.

Are you wearing a chest strap HRM or just a fitbit type thing on your wrist? If the latter, the figures will be pretty much meaningless. My friend and I did an experiment the other day with ours. We did the same weightlifting class using our normal weights - I lift a lot heavier than she does. We are the same age and have very similar physiques. I wear a chest strap HRM and she wears a top of the range wrist one. At the end of the class we compared results. Her recorded heartrate was much lower than mine and her calorie burn was double mine.

Michael Moseley, the Trust me I'm a Doctor chap did a programme about it which showed how unreliable the wrist monitors are. Having said that, of course get checked out, but don't rely on the info coming from your HRM in future.

It's an Apple Watch it has been pretty reliable until recently maybe I need to make an appointment with the Apple Store instead!

80bpm for a resting HR is normal?

It's not the watch that is the problem per se, it's that wrist HRMs are not as accurate as chest strap HRMs and indeed can be wildly inaccurate. Neither should be used medically.
