Definition:
Palpitation pertains to an abnormal awareness of one's own heartbeat; be it too slow, too fast, irregular, or beating at its normal frequency. The awareness is abnormal to the extent that the rhythm of one's heart interrupts the person's thoughts and consciousness.
Diagnosis:
The patient's own description of the palpitations is an initial indication of palpitations. This can be used as basis for further testing, which may come in the form of: routine medical examination; electrical tracing of the heart's activity (ECG); and blood tests to assess thyroid gland function.
Treatment:
Treatment options for managing palpitations include: beta-blocking drugs; intravenous antiarrhythmic medication; cardioversion; and atrial fibrillation.
Symptoms and Signs:
The primary symptom of palpitation is the distinctive awareness of one's own heartbeat. These palpitation attacks vary in frequency, and may last for a few seconds or as long as a few hours. Other symptoms associated with palpitation include: faintness, sweating, dizziness, and chest pain.
Causes:
There are a number of factors that can trigger palpitation attacks, including: physical overexertion; emotional or physical stress; excessive alcohol consumption; excessive caffeine consumption; certain drugs; as well as underlying conditions such as hyperthyroidism or thyroid malfunction. Frequent palpitations may be cause for alarm, as it can indicate a more serious heart problem. Palpitations are also generally linked to anxiety and panic attacks.
