I have one, and have seen that symbol a few times. Usually during a high stress moment, or a panic situation. I did some reading on it and from what I gathered they not only pick up true abnormal rythems, but also variations in heart rate while the monitor is on. So if you start taking your pressure and your pulse is 70, but then you start to get scared about the result and your pulse suddenly jumps to 100 during the reading, the monitor could get confused and see this as an arrhythmia. You can also get that warning if you twitch, or move around too much during a reading. Try to relax, because it's not something abnormal, and most likely you are perfectly fine :)
