At my last visit, my cardiologist told me about another patient who has POTS much worse than me, of course. His suggested treatment for this patient and all POTS patients is to "challenge" the cardiovascular system. By this he means, sit and stand up more often. Also, stay out of the reclining position and sit up right with feet flat on the floor. I once heard that this is equivalent to standing upright. He suggests more excercise in the vertical position and aerobically as well. It's not enough to do strength training, he wants aerobic movement. And this from the same guy prescribing oxygen and atenolol for me. I am asking, am I missing something here? Is this a correct mode of treatment for POTS?
