Im a thin boy but my main concern is that I can see my heart beat very clearly . When I put a hand over there I can feel blood coming and ventricles contracting this makes me feel so uneasy . By the way I have no structural heart problems ( confirmed by docs ) what scares me is that any slight trauma on my chest willake my heart stop.
It is most visible from left side between the 3 & 4 rib . I feel really uncomfortable while taking my pulse.
