Does your BP have to drop with the tilt table test to have pots. Iv fainted many times but they never catch the fall in bp, upon standing hr is 180?

POTS. In pots, the hr increases but the BP does not fall which separates pots from orthostatic hypotension. From your description, it sounds like you do have pots. It's hard to relieve the symptoms although there are a few things including medicines that may help. Good luck. Stay in touch with your doctor. Be patient as various treatments are tried or suggested.
