POTS ?

I feel like I have POTS.

My heart rate usually increases by 30 BPM when I stand up. But sometimes 50.

Generally, it increases systematically. I'm very anxious to begin with and morbidly obese, so I don't know if that plays a role.

Even so, if my heart rate jumps immediately when I get up, it immediately drops again.

Soaring. Until it stabilizes. For example it goes from 80 to 120, then it drops back to 90 in just a few seconds.

If I stand for a long time, it doesn't rise. It can be 80 or 90-100.

I have some symptoms, including dizziness probably associated with PPPD.

Usually I'll have some unpleasant sensations when I get up, then it will get better.

I don't react very well to very hot showers. I go up to 130. Otherwise, hot is fine.

All this happened after physical overwork in bodybuilding and lots and lots of anxiety. I spend my days being hyper vigilant and watching my BPM. I am going through psychological hell.

I did Holter ECG, ECG, ultrasound, Doppler.

As soon as I have severe anxiety, the BPM explodes. It happened to me that it went up to 190+ before an interview which worried me. Then it went down very quickly again.

I can play sports, but the BPM tends to be very responsive. To assemble very easily.

If I crouch down, the moment I get up, the BPM suddenly explodes.

What do you think?
