Looking for advice on POTS testing

I’m in the US I’m not sure where you are but my doctor mentioned a tilt table test but first I had to redo my echocardiogram and stress test. During the stress test he said my heart rate jumped so high when I first stood up that there wasn’t a need for the tilt table test. I might do it at some point but it’s not need now. They can pretty much tell without the tilt table test depending on how bad it it.
