Sorry, I know where you are going but the VAX did nothing to me except save me from getting sicker when I had Covid. My Afib issue's actually started well before Covid hit. Was at a point where I was probably in the best health of my life since my early 20's. I had dropped weight, was working out, all my blood numbers were great. I liked my beer, that was it. Never smoked. I just starting having Afib and had it for awhile before I knew what it was. It's estimated 1 in 3 people have it, again they just don't know it because they don't experience serious serious symptoms, have vague symptoms or or think it is something else like stress...which was me.
