Well...that sure sounds like something important! Glad it is nothing to worry about. I sometimes get what feels like an irregular heartbeat, mostly it is at night when I lie down after a very hard day. I nearly panic, then I tell myself to just control my breathing and it seems to correct itself finally. But that sure is a bad feeling, thinking something might be wrong, naturally you don't won't to go to the doctor for nothing, but then you don't want to "wake up dead"!!!
