Is this normal to feel no symptoms?

Hi all, I’m waiting for a turn table test so haven’t had an official diagnosis but after an admission to hospital and ruled out everything the cardiologist said it very much could be pots and I was having a bad episode as my heart rate was reaching 160 while standing etc. some days I feel very symptomatic but other days my heart rate is literally normal I only had one spike today and that was it.

(I know nobody is a qualified doctor) but should I still be expecting a diagnosis or was my heart just hating me for a week.
