Eric, I hope you find a doctor who is helpful. My cardiologist has often suggested Dr. Blair Grubb who is in Ohio. But I'm not sure whether Dr. Grubb knows anything about ME/CFS patients and so he may not understand those additional issues, especially PEM/PENE. It's a lot of travel for me, and I've never been convinced that Dr. Grubb could do much more for me beyond the prescription drugs that I'm already taking, so I've never visited him.
If you're up to it, then it would be great to get an update after you get an appointment with one of these doctors. Thanks!
Now, I hope you don't mind if I respond to heapsreal on this same thread...
Im only partially through the utube.
heapsreal, in case it helps, here's the PDF file with slides that go with the video -

I often have trouble watching pre-recorded videos (too long, can be very tiring) so I usually prefer looking at written material. Of course, these slides probably make a lot more sense when Dr. Rowe is explaining them.
It's cool to see the different slides showing what happens to blood pressure (BP) and heart rate (HR) for different types of Orthostatic Intolerance (OI). The POTS example is on page 11 and the NMH example is page 25. My diagnosis is NMH and, sure enough, my title table results are closer to what's shown on page 25. One difference is that my huge drop in blood pressure happens after 20 to 30 minutes, not at minute 6.
... my blood pressure is generally good and is usually high when the dr takes it(white coat hypertension).
Dr. Rowe often reminds patients that routine Blood Pressure (BP) measurements are not enough to diagnose Orthostatic Intolerance (OI). The patient's sitting blood pressure can be normal, or even high, and they may still have some form of OI. Even doing comparisons of sitting vs. standing BP may not catch the problem if you have a type of OI, like NMH, where the huge drop in BP comes after a relatively long delay.
From the Johns Hopkins printed material (see
http://www.cfids.org/webinar/cfsinfo2010.pdf for full document):
How are NMH and POTS diagnosed?
NMH and POTS cannot be detected with routine, resting blood pressure or heart rate
screening. The diagnoses can be made with a prolonged standing test or a tilt table test. Although
a 10-minute test is all that is needed to diagnose POTS, this is too brief for diagnosing NMH,
which usually requires at least a 45-minute period of upright posture. Many hospitals and
academic centers throughout the world perform tilt table testing. It allows careful measurement
of the heart rate and blood pressure responses to the head-up position, usually at a 70-degree
angle, in an almost standing position.
Regarding your questions about how different treatments work for different types of OI--NMH and the two(?) different types of POTS--I can't help much on the mechanisms behind them. But I have seen lots of online descriptions that might help. I can't wrap my own head around the medical details but you might want to browse around these medical research web sites:
* Vanderbilt University in Nashville, TN (
http://www.mc.vanderbilt.edu/root/vumc.php?site=adc&doc=4788)
* Center for Hypotension in NY (
http://www.syncope.org/) where Dr. Stewart does research (

I hope you get some answers!
