I am a 21 y/o female, and I've been diagnosed with POTS for about 7 months, although I've been dealing with it for much longer. I am going in to be tested for MALS soon with a vascular ultrasound, but I am concerned that my heart rate is too high in general. When I am sitting or laying down, it's usually between 110 and 135, when I stand up it goes to between 130 and 160, and with any light exercise (walking, walking up a hill) it goes to 160 easily (recently it's been getting to 195ish). Do other POTS people have similar heart rates? It's disconcerting to check my siblings and see them at 60-80 while I'm at 140.
