I'm not sure anyone will be able to answer this, but it's been bugging me for a while so I'll ask. I've not had an AF episode since April but if I do something that I associate with one of my known triggers such as eat a big meal late at night I get that 'funny' feeling in my chest/stomach that I associate with impending AF. When I get the feeling I automatically do deep breathing. My question is: what is going on, because my pulse remains steady (slow) and regular. Going by my pulse alone, there is nothing wrong so what is this impending feeling all about? I thought you were either in NSR or AF? I appear to remain in NSR but the feeling, often a bit like a lump in my upper chest tells me to be prepared. Anybody else experienced this?
I'm wondering if it's to do with the vagus nerve. I've actually experienced the same feeling going from a warm house out into the cold, or even missing a step unexpectedly.
