Should I be worried if I have an arrhythmia?

Some arrhythmias are signs of a more serious problem, while others are not. The irregular heartbeat can be brief and unnoticeable, but it also can be quite bothersome or even fatal. Because an occasional skipped heartbeat is not medically significant in the majority of cases does not mean that arrhythmias should be ignored. Notify your physician if you feel any skipped beats or feel that your heart is beating differently than normal.
