Yes I get that same feeling and it is scary when it happens. Try not to worry about it because it is a normal sensation with etopics.
I get that feeling and I hate it, it scares me. I get this weird constricting feeling in my throat along with the vacuum feeling during the skip then it leaves when the heart beats. It also makes me cough. It actually makes me sick to my tummy when I have a lot. I have been having them more than usual the last few days and I am panicking.
If I get a bad run of them it feels like it. Palpitations are so annoying.
Are you sure they are PVCS?
