Can they really use stable blood pressure as an excuse to say you don’t have anything wrong with you?

hiya, so following on from a particularly bad virus, I started experiencing very intense symptoms that I used to experience on a down low, I started getting increasingly more dizzy and I started passing out whenever I’d do anything like standing up really quickly and I got admitted to hospital for this whether they told me that nothing was wrong with me and I just needed to get further testing done.

I had a holter monitor. And after getting the results back, my heart rate was continuously high and correlation with the activities that I do and i’d written down, but I’m aware that they don’t use that monitor to diagnose. then I had some more detail testing done which wasn’t too difficult and something that they noted with that my heart rate increased a lot during these.

Then during the tiltable test I was so upset I didn’t faint the one time they really needed to faint. They were very reassuring though, and said don’t worry if you don’t faint we understand it’s only a snapshot in time, but getting my results back and then telling me there’s nothing wrong with me was really disheartening.

I requested my results for the tilt back, and saw that my heart rate increased from 95 to 156 and it stayed like that for about four minutes before going back down to about 120 and staying there fluctuating back up at times. There was a slight dropping in my blood pressure when I stood but bottomed out and levelled quite quickly.

so what I want to know is does this mean that I’m completely fine why did they tell me? I’ve got nothing wrong with me because my blood pressure was quite okay?
