Thanks to those who responded. I am already scheduled for a tilt table next week. I was just in the hospital and every time I got up out of bed my pulse would jump up about 50 bpm. I get dizzy, hot, and nauseous. Basically, I just feel awful. I have been on BP meds for 14 years and now they are saying maybe I never needed them. I am confused. If I was already on a beta blocker for my BP wouldn't that help? I am so frustrated.
