Report Can A Person With A Negative Ttt Still Have Pots? in Dysautonomia Discussion Posted September 6, 2009 Thanks potsgirl,I have considered redoing the tilt, and haven't ruled it out, but so far haven't done it. The main reason being that I am terrified of having another heart episode like the one I had (which I believe was a PSVT). I don't know if I can be strapped down on my back again while my heart feels like it is going to burst out of my chest. It was the worst experience of my life. I have no doubt that I have sensitive beta receptors, as I can't tolerate caffeine or really any stimulation that vamps adrenaline, and I do really well on beta blockers. So the thought of putting a beta atagonist back into my system.. man, I don't know if I can do it. I will if it's absolutely essential, but so far, everyone just seems really confused over my profile of symptoms. My POTS specialist highly doubts POTS, especially because she has checked my heart rate from laying down to standing a number of times and there's never really a change. Also, the other major reason I have decided against it so far is that my heart rate increase upon standing is very rare. Of all the times I go from sitting to standing, it probably happens like twice a week. So the probability of it happening during a tilt is super rare. If I were to take one right now, it would be negative. I'm sure of it. A heart rate increase upon standing is one of the symptoms lowest on my lists of frequency. For whatever reason, my insurance did not cover much of the ttt, and it took me over a year to pay it off each month. So I want to know it would produce results, and I feel like there's a really really good shot it wouldn't.Has anyone here had a negative one, then a positive one? Was it because you were like me in that the heart rate increases upon standing were infrequent, and you finally had a tilt catch it?
