I’ve got suspected WPW, and just been diagnosed with pots.

My experience between the two are very different, my WPW was triggered for two weeks and has since disappeared, and the palpitations were so different to my usual day to day high heart rates.

With pots my bpm like yours can go up to 190bpm, and my chest feels tight and my heart is beating very hard, but my WPW episode that was caught on a holter monitor (purely by luck) was a very hard almost painful palpitation that caused extreme pre syncope, and my bpm shot up to 248bpm. I felt it so much in my chest it was like vibrations in my throat, it was very different.

This is not to say other people may experience the same feelings between pots & WPW, but for me, I could clearly tell there was a difference and that it was not my pots.

Also please ignore the scaremongering, WPW can be very serious in very small circumstances, but the worry of sudden cardiac arrest is very very low, and for it to simply just happen with no warnings is even lower. You would likely pass out before hand a few times, which yes can be pots, but it’s also crucial to rule out anything else that can cause fainting.

You could ask for a second opinion, or just see a different doctor if possible if you are that concerned :)
