How dangerous can it be if your heart skips a beat? My heart does this weird skipping beat thingy every once in awhile.... I notice it more if I ve drank coffee. Anyway, it feels pretty weird and I ve even seen a cardiologist who couldn t find anything wrong. Is it dangerous if my heart does this several times in one day??? Is it weakening my heart or anything? to Police: Not only are you an idiot with horrible spelling skills, but you are also a rotting cunthole.
