What are palpitations? are they the same thing as flutters?

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.

Yes: When the heart's rhythm is interrupted, as it is in virtually all normal people everyday, it's usually not felt. But when it is felt, the feeling is called a "palpitation". Many people perceive the irregularity as a "flutter".
