Hi 16287. I haven't actually fainted but have had blood pressure so low 85/46 where I was dizzy for several days straight and my vision was spinning. Very frightening.
Here is a link that explains the QSART test better than I can. It is a painless test and you are completely awake. Nothing enters your body, just electrodes are placed on the lower portion of your leg and on one arm. I strongly suggest you have it done.
There are different types or symptoms of autonomic dysfunction. The umbrella term is called dysautonomia.
I am not a neurologist, however I am well read. And from what I read all symptoms possible that are truly caused by autonomic dysfunction all are associated to miscommunication of brain messages through our nerves to our autonimic body functions.
I have not had the tilt table test and have chosen not to get one because I don't think they are clear and definitive. Lots of people could get dizzy or have their blood pressure go out of wack from being positioned in different angles on a table. Who knows, it could be a med they are on, whether or not they are properly hydrated, etc.
However the QSART test truly tests the nerve communication and response to the sweat glands. From what I understand a person with true autonomic dysfunction will either perspire excessively or very little to none. I did not sweat. I feel hotter than most people where they may feel comfortable in a room. But when i open windows or blast the air conditioner I feel good at the moment but later that night I get head to toe body aches.
My QSART test was done at the neurological center at JFK hospital and my results was read by a trained licensed nuerologist specializing in the test and the condition. My own nuerologist didn't have me do the tilt table test, he said go straight to the QSART test. We want to make sure we have the correct diagnoses.
I have almost all of the symptoms. Low blood pressure and orthostatic hypotension. I take midodrine daily to raise and maintain BP.
I take a beta blocker to control my tachycardia - rapid heart rate which is troublesome for me in spiratic times. My heart was fully tested and I don't have a heart condition. I had an echo, stress test and 30 day holter monitor. All clear, so it is my autonomic condition making my heart race at times.
I battle raging fatigue. I now take a medication nvigil, now generic armodafonil. That med is a God send. I was sleeping 12-16 hours a day previously. Now I can get by with only 9-11.
I deal with constipation and body pain. I also have action tremors in my fingertips. I have no idea if that is related to the AD.
Unfortunately I have most if not all of the symptoms.
I wish you well and i am glad you are here to share.
