Twice in the past 3 days I've felt this weird like flutter in the center of my chest. The rust time it felt like a thump and then a flutter then just now it was a flutter. I had an ekg, blood work, and a CT scan on Thursday and the dr said everything looks fine. A little over two weeks ago I had a 24h ekg done and everything was fine then too. Are these flutters really just anxiety? They freak me out bc they come out of no where! The one I just had happened while laying on the couch watching tv. Anyone else get this?
