This is what I read on a few sources, but I'm not sure if it is always true. I get some ectopic beats that are followed by a long pause and a forceful thud, but most of my ectopic beats blend in quite well to the underlying rhythm. There is usually no pause, I just feel an uncomfortable beat in my chest and my heart just resumes beating normally. I also noticed that preceding some of my ectopic beats I feel a tickling sensation in my chest, like an air bubble expanding in my chest. Sometimes this tickle doesn't produce anything, but sometimes it leads to a single premature beat or a burst of 2-4 premature beats. Again, there is almost never a pause after this event. My heart just continues on as if uninterrupted. Does the tickling and the fact that there is no exaggerated pause after the ectopics have any value in discerning where in my heart these ectopics might be originating?
