Ignored?

I’m almost 99% sure i have POTS. My cardiologist made me do a stress test, I tapped out at around 7 min. I wore a holter monitor for 2 weeks. I told him all my symptoms: my HR jumping with standing, raising my arms, my exercise intolerance, etc.

He reviewed my results, & saw the spikes, extra heart beats (he said harmless PVCs), & also the fast drops in my HR.

He said “this looks like an arrhythmia” then proceeded to put me on 12.5mg metoprolol. No other tests, NOTHING. Didn’t even reassure me if it was harmless, etc. I left the office anxious bc wtf? Maybe it’s not pots then? Idk anymore.
