Tachycardia causes?!

[Kelloggs31]

I've had some unexplained sinus tachycardia at the moment which is under investigation. I've had to have a month off work so far because I work in healthcare and untill we know what's causing this I can't look after patients which I understand. However I'm scratching my head at of there's any ideas any one has?

I've had normal routine bloods which are normal, thyroid normal, d-dimer normal, iron levels normal, magnesium normal. Chest X ray clear and an echocardiogram where the only outcome is my tachycardia of 140bpm at rest.

I've had persistent tachycardia since November. Ranging from 120s-150s resting.

I've got a 24 hr tape on Wednesday. But fear I'll just get the response sinus tachycardia which we know already and told again I can't work until diagnosis is found.

Does anyone have any ideas? Or tests I can request? I'm keen to go back work asap

I'm only in my 20s

No other health problems

Last recorded heart rate in 2018 was 70bpm

I don't have the same problem as you. My resting heart rate is 55-60. However, I do notice that if I am stressed or drink alcohol that it goes up by about 50%. Is that something that could explain part of it? Hopefully they'll sort things out for you soon.

Hi, I'm new to this site. I've just read your post and no joke it was like reading my own problem at the moment. I also work in health care and have been off work since the beginning of February, they won't let me return until I find out what's going on. 24hr tape showed runs of SVT 177bpm at random times. Bloods, ECG all normal. Now on bisoprolol 1.25mg daily to help keep rate down as BP normal. Waiting for an echo which is like pulling hens teeth!!! Can I ask how you are doing now? as I noticed your post is from a while ago.
