Thx! I haven't done a TTT, but my cardiologist checked HR and BP laying down, sitting, standing - and noticed a large enough increase that it def. wasn't normal and very close to POTS numbers. He doesn't believe in doing the TTT if he is confident of his diagnosis from symptoms and the few numbers he gets. I def. have the symptoms. I have never completely passed out, but come very close - especially in heat. Failed stress tests but the echo-stress was normal (plus the zillion other cardiac tests I have had over past 4 years). Soo dizzy constantly, with brain fog, chest pains, occasional shortness of breath, etc. Salt does usually help, which is another reason why they are confident this is POTS (or a type of dysautonomia).
I just started Bystolic to see if it helps. I have had daily life impact recently from constant nausea and increased fatigue. So far I can't tell a difference. I've been on it for ~2 weeks, and yesterday I had mostly very high BP. No idea what caused that. It was ~156/70 most of day, interspersed with low numbers. HR stayed ~60. Today I am back at my standard 95/61 BP most of day. I also tried Florinef in the past, but was allergic (so sad, as I felt AMAZINGLY energetic).
Hoping to level out and feel better soon. Hot summer weather is not our friend!
