palpitation

 [pal″pĭ-ta´shun]
a heartbeat that is unusually rapid, strong, or irregular enough to make a person aware of it, usually over 120 beats per minute, as opposed to the normal 60 to 100 per minute. In most cases, it is the result of excitement, nervousness, strong exertion, or taking of certain medications (including caffeine and nicotine). There are also palpitations that result from heart disorders such as paroxysmal tachycardia, flutter, abnormal rhythms in which the heart has runs of rapid beats, and atrial fibrillation (in which the beats are rapid but irregular or seemingly random).

Palpitations may be caused by organic heart disease, but they also can result from other factors. Similarly, emotional pressures rather than organic changes may cause the so-called “nervous heart,” or functional heart disease.

Etymology: L, palpitare, to flutter
a pounding or racing of the heart. It is associated with normal emotional responses and with heart disorders.

palpitation

Palpitation

Rapid, forceful, throbbing, or fluttering heartbeat.

palpitation

beating of the heart of which a person is strongly aware, as being rapid and/or forceful, or sometimes irregular. May be both unpleasant and worrying but most will experience palpitation on occasion. Physiological causes include exercise, excitement, caffeine intake, smoking and alcohol. May also be a symptom of underlying disease, e.g. anaemia, hyperthyroidism, cardiac disease (especially if linked with other symptoms such as faintness, sweating, chest pain). Investigations (ECG, ambulatory monitoring, echocardiography, exercise test) are used to identify the nature of the condition and possible underlying causes.
