Post covid fast heart rate

[Robbie1964]

I got covid 4 weeks ago after returning a positive test after days of feeling awful. Among all the symptoms, one thing I got was a fast heart rate. I'm on Bisoprolol (1.25mg, a very low dose) as well as lisinopril and lercanidipine (both 20mg). By fast I mean around 75 to 90 while resting with my heart rate heading to 100+ while exerting myself. Prior to getting covid my resting heart rate was always around 60-65 with my heart rate after a decent, fastish, 30 minute walk heading to around 90-100 but quickly falling back to under 70 within 10 to 15 minutes of resting.

I subsequently tested negative for covid two weeks ago and had assumed that the effects would quickly vanish. However they didn't. I had an awful dry cough until a few days ago, couldn't get a lungful of air (that's now easing up), felt exhausted (that too is getting better) and had terrible palpitations too on top of the fast heart rate. The palpitations have now gone (hopefully), again like the cough they went a few days ago. However, if anything, my heart rate seems to have got worse not better.

As a short term thing I've increased my Bisoprolol dosage to 2.5mg - normally this would slow my heart rate down to below 50 - but it's not making much difference to be honest. I should really speak to my GP soon as I will run out of Bisoprolol tablets a week early. However my usual GP is on holiday for the next two weeks and I have little faith in the other two GPs in my practice. One seems not to care about the patients and the other hurries you in and out the surgery including trying to put on the blood pressure meter cuff on my arm before i have even sat down - the end result is that my blood pressure readings are all over the place when I get it taken at the GPs (except by my usual Doctor who does do them properly). In the past this has led to my medication dosage being unnecessarily increased because the blood pressure meter readings were done in a hurry while I wasn't relaxed. My readings are fine when done at home. I don't want to go to the Doctors to see about my heart rate and come out with more blood pressure tablets.

Has anyone had covid, had problems with their heart rate and found that in time the problem went away? I have to play safe as I have had two heart attacks (one in 2010, the other in 2021). On the other hand I don't want to come away from the Doctors frustrated by the GP hurrying things along and just giving me more blood pressure medication when I may just need a temporary lift in my prescribed beta-blocker. The othee thing is that the definition of fast heart rate officially means above 100 and mine isn't when resting. It's just that having had two heart attacks I prefer to keep it closer to 60 than 100.

The NHS guidance is to contact the GP in the above scanrio but I think that may be if the fast heart rate is still there 4 weeks after having had covid. I got it 4 weeks ago but didn't test negative until two weeks ago.

Thanks in advance for any answers or guidance anyone can give.
