Random dizzy spell and slower heart rate when sit down from standing position

[natsss]

Hello everyone. Has anyone felt this before. Sometimes when I stand up, and sit back down on the coach quickly, I get dizzy and my heart rate feels like it slows down; takes a few seconds to go back to normal, then I feel fine. This only happens when I sit down (like thump down on the coach kinda hard) Any idea what this can be? I used to see a cardiologist quite often as I was diagnosed with SVT and PVC. All my test come back normal and doc says my condition isn’t serious, I’ve also had what looked like an ultra sound on my heart, doc also said nothing structurally is wrong. This weird feeling is so annoying. Kinda worries me too! Anyone feel this?

Just wondering if you could have POTS, which is caused by posture change.

Have a look at this recording Dr Sanjay Gupta has made about it:

I’ve heard of POTS! I’ll ask my cardiologist about it next time... oddly enough I’ve had a 3 day monitor on twice already and when I got results back both times they said everything looked normal...last one was in 2015. But I do have cardiology check ups often, just had one July 1st where they did check up on heart rate in the clinic. I love watching Dr. Sanjay Gupta. I asked my doctor if I can take magnesium supplement, showed him which one I bought (after watching Dr. Sanjay Gupta’s video) and they helped me a ton with PVC’s (skipping heart rate/flutters) thank you for the reply!

I'd consult my cardiologist ASAP.

I already did, July 1st. Tests came back normal... but i thought I’d ask to see if anyone else has experienced this before ? Just an odd unusual feeling. No pain or anything, just super uncomfortable.
