Saw a cardiologist to rule out POTS/autonomic disorders - she told me all my vitals are normal but I'm not convinced entirely

Hey yall. I've been struggling with feeling faint, fatigue, cardio health, blood pooling, and chronic Tachycardia for years. I've had a 7 day monitor and it showed 2 days straight of my HR staying above 100, but I got covid halfway through so most of the readings are me sleeping all day haha.

My doctor is the one who suggested maybe POTS and sent me to get an echo and see a cardiologist. The echo was mostly normal except a valve prolapse and some regurgitation in all 4 valves. The cardiologist said everything was normal and measured some vitals in office

Where my HR started at 70, and stayed 100-120 for all 3-10 minutes. Which she said was normal. My blood pressure stayed above normal the whole time with a spike at 3 minutes but nothing crazy at all.

However she told me to try it at home if I ever feel off or my usual symptoms and

Base laying: 93/66 66bpm

3 min132/95 HR 96bpm

5 min 116/72 129 bpm

10 min - Didnt last. Stopped at 8 Felt faint, started sweating, felt like vomiting, vision started to white out. Laid down on bed - 111/72 56bpm hands tingling for 30 minutes

I sent this to her and she told me that is still all within normal parameters but I lm really not sure. I also have Lupus but I'm not in a flare and I've had these symptoms longer than SLE

Anyways, any advice? Is she right?
