Hi I am dignosed with IST(inapropriate sinus tachycardi), a similar condition to POTS, or at least overlapping. My diagnosis process has been lackluster taking many months, and requring me to seek private specialists, in a country of state hospitals.
I am worried about my heart rate. It seems to meet the POTS criteria. WIthout any meds my resting heart rate will be 80-90 in the afternoon, but this will rocket to 130 or more when I stand up. What is a norml resting heart rate in POTS, and how big is the increment upon standing. Is the high heart rate dangerous?
