possible hyperpots?

i’m f19 getting evaluated for pots, rheumatologist said i had it after doing active stand test but nothing on paper. been having really horrible fainting episodes and i did a poor man’s tilt table at home.

lying down: 115/70, 60bpm standing 1 min: 145/90, 100bpm standing 5 min: 80/40, 120bpm standing 8 min: 168/91, 131 bpm fainted around 9min 30

anyone have any insights? i’m genuinely at a loss and idk what to do. when i did this i was wearing compression socks and had had 3+L of water. wary of increasing sodium since i have had a DVT. any help/advice is greatly appreciated <3
