A real good explaination

This is about POTS, but, POTS and OHS have almost 100% identical symptoms and will present the same unless you have a blood pressure monitor connected at the time.of your episode, which I did. I also had both a Physio and Occupational therapists with me when I presented. Thank goodness for that as they were able to talk with my team of physicians what was actually going on, my heart rate, blood pressure and respiratory rate plus how I was reacting at that time.
