VTs, SVTs and chest pain

My cardiologist is admittedly not well versed in POTS. I have POTS (TTT diagnosed) and random bradycardia events he just changes the subject about when I mention them. 42 seated upright maybe 3 - 4 times a month.

My last holter came back with 4 VT events that lasted less than 10 seconds and several SVT events. Considering thr bradycardia events and these findings, plus orthostatic hypotension, and random extreme chest pain - are these events expected with pots?

My last echo was over a decade ago. My stress test came back acceptable. My TTT shows a drop of 10 bp wise upon the 1 min mark (rapid expected POTS HR increase) then a rise in bp the next minute, then decrease the next etc. The 10 minute test caused loss of feeling to feet, shaking, peripheral vision tunneling.
