Hello all. I am so glad to have found this board, and people who can understand what I am going through! I have not been officially diagnosed yet (because my doctor is a bonehead), but I strongly suspect that I have POTS. I began passing out and having "episodes" in mid-September of 2007. Since then, my condition has worsened, and now includes extreme fatigue, weakness, dizziness, tachycardia, flushing, insomnia, feeling cold but being very sensitive to getting too hot also, and hair loss. I haven't been actually passing out as much, but do still have the "almost passing out" feeling where I need to sit or lie down right away. I have some good days where I almost feel normal, but the bad days are SO bad... My doc had me go in for a tilt table test, and this is the part that I'm not sure about... I did have the 30+ bpm increase, but it was within like 15 minutes and not the 10 that I've read is the standard... is there such a thing as delayed POTS? Or can this still be considered POTS? How hard and fast is that 10 minute rule? Also, when the 2nd part of the test was done (where they give you the adrenaline stuff), my heartrate skyrocketed within the first 5 minutes and I became very ill, so ill in fact that the tech ended the test early. According to my doctor, this is a normal test result (really?), and when I suggested POTS, he said that "POTS is an emotional disorder". I told you he was a bonehead. I'm currently seeing a new neurologist, actually just started seeing her. I went in today for an MRI, which I'm sure won't show much, but I'll jump through the hoops if I have to. She has admitted that she does not know anything about POTS, but I think she is more open to referring me to a POTS specialist than the old doc would have been (he just basically dismissed me as being crazy, although he did prescribe Atenolol at my insistence that it was POTS, which seems to be helping, so I guess I have to thank him for that)... Any info that any of you can share is greatly appreciated. I guess I'm basically just looking for reassurance that what I'm experiencing is real, and that I'm not just crazy, as everyone around me, who've never gone through anything like this, seems to think. **Sorry, I forgot one question, so I'm editing my original post- does anyone know why I would have had such a strong reaction to the artificial adrenaline stuff during the tilt table test? Is this a POTS-type thing? Mary
