My cardiologist did not do a tilt table on me. She did the lying down, stand up test; a holter monitor; an EKG; and a heart sonogram. I don't have my test results, but she felt certain it was dysautonomia.
That's a shame, it would have been good to see your "before and after" figures for the tilt table test.
But no doubt your doctor has conducted the right tests in order to diagnose dysautonomia. Did you doctor specifically say that you have POTS, or just dysautonomia?
Dysautonomia itself is an umbrella term which covers a number of types of autonomic nervous system dysfunction, including POTS.
It will be interesting to see what your doctor makes of it when you go back at some point and get retested.
I have not seen any improvement in my POTS since I started this experiment in earthing during sleep, 5 days ago. Just before I started this experiment, I measured my lying-to-standing heart rate increase, and there was a jump of 32 bpm (I had 78 bpm lying, rising to 110 on standing).
Then this morning when I measured it, I had a lying-to-standing jump of 30 bpm. So no real improvement. My POTS heart rate measurements are always around the 25 to 35 range. When I do regular excerise like running for a few months, I can get my lying-to-standing increase down to around 20 – 25 bpm, but normally I hover around 30 bpm.
I'd be interesting in learning what your lying-to-standing heart rate increase is. One very convenient time to measure it is when you first wake up, as you are already relaxed and lying down. To do this, whilst lying down in bed, count your pulse over 1 minute using say your bedside alarm clock, and note your heart rate down. Then get out of bed, stand up, wait around 90 seconds, and count your heart rate again, while standing. As before, if you get a jump in heart rate of 30 bpm or more, then you have POTS.
The amazing thing about POTS is that it is incredibly simple to test for and diagnose.
