Very low HB occasionally after ablation

Has anyone else got this? had my ablation just under 1 month ago (it was problematic but OK now) HB has been fine with median 55-70; regular and am getting better all the time. However on 2 occasions my HB has fallen very low; it does not last for too long (a few hours). A couple of weeks ago my HB went down to 39-40 and yesterday at times it went down to 36 and hovered around 43.

My app is accurate; I was not feeling that bad - just a little tired, slightly lightheaded and spacy - but more scared than anything else. I lied down for the afternoon and read and by the evening it was back to normal. My next appointment should be in a couple of months time (probably longer as Barts' computer still not back up so I am told) and I really cannot cope with A&E and my doctor would just send me to A&E.

Before I got AF my HB was always quite low at 50 (I am no athlete it was just like that) and then I got in permanent AF with it going up to 200 and with a median of 135.

Anyone else got this and know what it means?

Thank you

Being dehydrated can make your BP drop, make sure you drink plenty of water. Honestly it makes a big difference.



I very rarely check my heart rate but it can be a bit low and I don't feel it's a problem for me as I don't feel inconvenienced in any way or breathless. Like you I'm not an athlete but just tend to have a slow pulse. It was 40 when I had an ECG a few weeks ago and no comment was made. After my second ablation my heart speeded up to about 70bpm and that felt very odd and I was glad when it slowed down a bit.

For me 40 - 50bpm has been normal for years on Bisoprolol.

I came off it earlier this year and am now between 45 and 55 when resting most the time.

We are different but for me it is not a big problem except being more aware of the odd ectopic beats and missed beats.



thanks good to know not that unusual
