I have occasional sensations around my heart , almost as if something inside is brushing past it, and the feeling of either skipping or half skipping a beat. My heart beat dosen t usually seem the increase, but the feeling of my heart beat gets more weighty, as if it is pumping more heavily, but not at noticeably increased speed. I m a healthy 25 year old man with no previous heart complaints, I m 6ft 2 and weigh roughly 12 1/2 stone . It isn t at all painful, in fact it can almost feel pleasant as the sensation is unusual. It only happens when I am at rest, but has happened standing, sitting and lying down. I m not too worried, but concerned that it should be something I should talk to my local GP about. Thanks
