Incorrect diagnosis of Vasomotor instability?

[Sophiab123]

I recently went to the cardiologist and got the diagnosis of vasomotor instability. For the past several years I have had symptoms of POTS. I wrote down my various sitting, lying down, and standing heart rates from the past few weeks as evidence. My resting hr is around 68 and standing, it can get to 130. He disregarded all of this information and suggested I drink more coffee and tea. Previously to this the nurse wrote down that I don't drink coffee because it makes my heart race. I asked him at the end of the appointment, after he made his diagnosis, if it could be POTS. He said no, because he reserves that diagnosis for the very severe patients. He basically brushed me off because most people pass out. I've fainted a few times in just the last few months. I am very sensitive to temperatures. I get very dizzy standing too log. All my symptoms match up with POTS. Do I have POTS, or was this cardiologist correct in his vasomotor instability definition?

You need to go get a second opinion. If what you're telling me here is correct of what this doctor said, he seems to have a mistaken understanding of the diagnostic criteria of POTS. (Which is not uncommon really.) Incidentally, vasomotor instability is a symptom, not a diagnosis. This is pretty readily apparent if you search this term on pubmed or scholar.google.

I would definitely recommend seeking out a second opinion from someone with demonstrated experience in this field. If you PM me what state you are in (or what country if outside US), I may be able to recommend a hospital or specialist.

Best, Heiferly.
