Wikipedia Meaning and Definition on 'Palpitate'

A palpitation is an abnormality of heartbeat that causes a conscious awareness of its beating, It can be caused by (but should not be confused with) ectopic beat, which is a more specific diagnosis.

The difference between an abnormal awareness and a normal awareness is that the former interrupts other thoughts, whereas the latter is almost always caused by a concentration on the beating of one's heart. Palpitations may be brought on by overexertion, adrenaline, alcohol, nicotine, caffeine, cocaine, amphetamines, and other drugs, disease (such as hyperthyroidism and pheochromocytoma) or as a symptom of panic disorder. More colloquially, it can also refer to a shaking motion. It can also happen in mitral stenosis.

Nearly everyone experiences an occasional awareness of their heart beating, but when it occurs frequently, it can indicate a problem. Palpitations may be associated with heart problems, but also with anemias and thyroid malfunction.
