Advice on getting a POTS diagnosis

My PCP sent me to a neurologist who diagnosed me through a autonomic testing (tilt table test)

my pcp sent me to a cardiologist who then sent me to a POTS specialized cardiologist which is how I got my autonomic function test set up. took many months in the making but my process was a little excessive

You need a referral from your primary to get a cardiologist. Press for a tilt table test for a diagnosis.

I personally got a referral to Stanford and had autonomic testing done; in the meantime like you are currently doing I recorded and monitored my heart rate and symptoms. I had to go without meds a few days prior to my testing. I received a diagnosis day of my testing! Good luck I hope you can get in to see someone, I know the relief it gave me 🙏
