Cardio tests
Hi, Creekfeet; besides the tests you mention when you see a cardio, it might be worth asking if impedance cardiography is available (aka Plethysmography)--this is the non-invasive measurement of blood volume supine and standing that was used by Peckerman in the essay that largely triggered Paul Cheney's "The Heart of the Matter," and which has been further incorporated into his more recent work on cardiac issues in the latest DVD.
I have discovered that there is a private clinic in Vancouver that uses Physioflow Enduro, a version of impedance cardiography, and I intend to go over there soon to have this done--$150, and I think well worth it. It can show if you have the low heart output that is so characteristic of CFS, and that gets missed by most cardios, as Cheney describes. I would just love to have such evidence to wave beneath the nose of the next cardio I see!
Best, Chris
