[|Human|] I was recently diagnosed with Postural Orthostatic Tachycardia Syndrome. I am taking Fludrocortisone and Metropolol, but I am still very symptomatic and they are making me depressed. I will be seeing a specialist next week so is there anything I should ask him about? What can I do to help prepare for this appointment?
[|AI|]  Hello! Welcome on Chat Doctor ! I understand your concern and would explain that your symptoms are related to an autonomic nervous system dysfunction, which causes orthostatic intolerance. Head Up Tilt test is the best test for the diagnosis of this disorder. I agree with the medication you are taking too. Another possible test to consider would be anti-ganglionic acetylcholine receptor antibody levels. They are usually increased in this situation. Hope you will find this answer helpful! Kind regards,
