ad quite a bad cold about 2 weeks ago,it lasted a week and now I am left with a cough. I noticed a couple days ago I have started with the odd heart flutter which panics me. I know there is a condition that can be fatal which is an enlarged heart as a result of a viral infection. symptoms are palpitations,tight chest,chest pain and having had a cold or flu. I don't have chest pain or tight chest but I am getting heart flutters and have had a cold. I think my symptoms have become works since thinking this but i can't be sure as now i am constantly worrying Im going to have a heart attack. I have been under a bit of stress the past week but not enough I didn't think for panic attacks. I feel so worried
