Low sleeping heart rate and blood oxygen

[Jimjimjeroo]

Hi All, I'm one of those "Smart Watch" people, so please bare with me! 40 Year old Male,

Over the past few weeks I have been checking my sleeping heart rate after a comment from my surgeon. During a recent anaesthetic it was noted i had a very low heart rate. On average its between 30-35bpm. This is over a 6 hour period, where it does rise

Then I noticed my blood oxygen levels! This drops as low as 70% over night, but quite often below 85%

Currently awaiting 24hr ECG.

hi I don’t get low heart beat (58 lowest) at night but I tend to get low levels of blood oxygen - 80% lowest ranges between that and 95% but does go over 95% (not sure but could be higher when I wake up repeatedly in night). I too have a smart watch. I can get drops in day not regularly.

I discussed with GP and he didn’t hesitate to refer for sleep study albiet I have other risk factors than just heart issue and asthma.

👍

The ECG should give you some answers. Meanwhile, is your watch positioned OK? It should be above your wrist and fitted snugly (but not too tight!)

You could splash out £20 or so on a heart rate chest strap which communicates with your watch. They're generally more accurate than the optical sensors on a watch. However, when I tried sleeping with one on, I found it too uncomfortable (it's a strap that I already had).

Your figures do seem really low, even for an athlete but I have no medical qualifications so what do I know.

Since you have an ECG arranged, I assume there's a doctor involved.
