I've had palputations and fluttery heartbeats for years and its not something that usually bothers me anymore I just ignore it till it goes away and it usually does it not much time at all, but 3 months ago I got them loads for like 2 weeks solid, got checked out at the doctors and had an ecg and chest xray and was given the all clear, but now i've got them again and had them pretty badly for 3 weeks now, wondering if I should go get checked out again because im not feeling very anxious at all infact I feel pretty good aside from my heart.

thanks
