POTS or not?

Done this morning and i think i really need to follow up on this.
My heart rate is clearly elevated and my systolic pressure drops quite low until the 5 minute mark. Diastolic increases after 10 minutes. Oxygen keeps dropping and then stabilizes around 93/94 %.
My pulse pressure looks very low as well.
What do you guys make of it?

I turned off the airconditioning because my orthostatic intolerance is worse when it's hot.
I'll try again tomorrow with the aircon on and the room temperature set to 23 degrees celcius.
