Palpitations occur when a person can feel abnormalities in the normal beating of the heart. These palpitations can be an isolated extra beat, or they can run together and last for prolonged periods of time.
The symptoms of palpitations vary from patient to patient with some common features. A perception of irregularity of the pulse, an uneasiness in the chest, a flip-flopping in the chest; frequently people describe their palpitations as "my heart stops." Certainly a feeling of strong pulse throughout the chest, head and neck could well be described as a palpitation.
Other expressions are, 'skips a beat', 'heart turns in chest', 'flutters', 'tickles in chest', 'butterflies', 'heart jumps out of chest', 'hammering in chest' etc.
