Autonomic Clinic at Stanford Refused My Cardiologists Referral

Two of my Doctors (PCP and Cardiologist) have said I have an Autonomic Dysfunction and got a referral to Autonomic Clinic at Stanford, which Stanford refused. I was a little encouraged that I maybe able to get treatment and diagnoses and quit smashing my face by passing out.

I live in the Bay Area and am wondering where to turn next, or maybe I don't have an Autonomic Dysfunction. My tachycardia, arrhythmia, syncope, vertigo and dizziness are all real and measurable, but I don't know why.
