| | Palpitation - Wikipedia, the free encyclopedia |
 | | A palpitation is an awareness of the beating of the heart, whether it is too slow, too fast, irregular, or at its normal frequency; brought on by overexertion, adrenaline, alcohol, disease (such as hyperthyroidism) or drugs, or as a symptom of panic disorder. |
 | | Palpitations may be felt with heart problems, but also in anemias and thyroid malfunction. |
 | | Palpitations alongside other symptoms, including sweating, faintness, chest pain or dizziness, indicate irregular or poor heart function and should be pursued. |
