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.

Very much so: But if you find the sensations to be bothersome or are have any lightheadedness or dizziness or exercise induced, you should review this issue with your doctor.
