Palpitation Sx: Palpitations are an awareness of extra heartbeats which most of us have. The sensation can be single or multiple and can sometimes last minutes. Different people may feel other symptoms along with them such as dizzy, lightheaded or short of breath. The palpitations are almost always atrial or ventricular premature beats. Usually benign but they are also found with abnormal hearts.

Probably not: Although heart palpitations are common, they should not be considered "normal." the best approach to finding out about your palpitations is to see your doctor and get an ekg, preferably during a time when you are having them. If your palpitations occur every day, a 24 hour (holter) monitor would be useful. If they occur less frequently, a more prolonged (2-3 week) monitoring period may be helpful.
