Hi, I am a 30 year old active male. Over the past month or so, I ve experienced fluttering on a regular basis. I had a complete stress test done last year with my cardiologist and everything came out fine. Not to mention, the other EKG that was taken several months later that also came out fine. I usually get the fluttering after consuming caffeine, when I m anxious or overwhelmed, or stressed. Anything to worry about? Thanks
