Have your doctors done any testing or evaluation for IST (inappropriate sinus tachycardia), POTS (postural orthostatic tachycardia syndrome), or any other forms of Dysautonomia (autonomic dysfunction)? From your description, I think that might be the next route for you to explore. Feel free to post in the Dysautonomia Community here on MedHelp if you have any questions about these disorders. Best wishes!
