    Another source/resource for CPET testing.

    The two tests sites I see on the forum were a bit of a journey, we live in TN. I dug around the internet and found a company that sells the test equipment. I emailed them thinking they would at least know who has the equipment, and that may be a good way to find one near you. A very...

    Unexplained exertional dyspnea caused by low ventricular filling pressures: results from clinical invasive cardiopulmonary exercise testing

    This isn't about ME, but some of the patients had POTS, and this is discussed in the context of exercise testing. Thought the results might be of interest to some here. I have pulled out one of the relevant sections and quoted it (below the abstract)...
