Firstly, I haven't been diagnosed, but pretty sure I have this. Increase of heart rate by about 40 bpm measured on pulse ox from laying down to standing position and can feel my head pounding. Sometimes I feel dizzy, quite out of breath walking up the stairs and generally tired.
At the start of last year I paid privately to see a neurologist as I was suffering from one sided headaches, pins and needles, weakness, brain fog and derealisation - MRI of brain came back clear and was put down to low ferritin and stress. Did improve and never suffered from a racing heart.
Had covid in October and all these racing heart/tachycardia episodes have definitely got worse since then.
Went to a&e last month with a resting heart rate of 136 but they said I have a fever when I got there and didn't really know why I was tachycardic. Since having my booster vaccine last week, I've been unwell and heart symptoms are worse. I feel as though I have adrenaline in my chest if that makes sense? Which quickly passes and I'm not anxious! Also feel breathless when standing up and doing minimal movements. Also suffered on and off with chest pain which changes for the last few weeks.
Have had a 24 hour ecg and heart echo that came back normal. All bloods normal and blood pressure normal too.
Seeing a private cardiologist on the 17th but have work tomorrow and feel really nervous about these symptoms.
Does anybody recognise these as symptoms of PoTs? I'm really worried I have a problem with my autonomic system!
