Did you have anxiety before you had palpitations?
Or did the palpitations start first?
My guess is that, generally, we suffered from various anxiety symptoms for a long time like GERD, IBS, panic attacks, etc. then the palpitations started.
That was certainly true for me.
My thinking is it might be a bit more reassuring if we discover most of us suffered from anxiety first and then various effects of that.
It supports the idea that anxiety is the cause and that palpitations are just another symptom.
