Pots?

I had an appointment with my NL today. My blood pressure is still low, still having major fatigue and dizzy spells. He finally decided to send me to Cardiology for a consult, echo and a tilt table test. My bp was 80/50. The fatigue is killing me and I feel like the life has been sucked out of me. He even said that my paleness worried him. But two weeks ago he didn't seem to think it was a problem. I am just tired and grumpy! What else is new. lol

I guess my question is...what exactly do they do for the tilt table test? And if anyone has any experience with this stuff, please feel free to comment! Thanks a bunch!!!
