A heart palpitation is a medical term used to describe the feeling that the heart is racing or pounding. Some of the most common causes of heart palpitations include anxiety, caffeine, nicotine, or strenuous exercise. In some cases, the causes of heart palpitations are more serious and may indicate heart or thyroid problems. For this reason, any recurrent heart palpitations should be reported to a doctor for further medical evaluation.
Stress and anxiety are among the most common causes of heart palpitations. The heart typically returns to a normal pace once the stressful ordeal is over. Those who suffer from anxiety disorders may notice these palpitations as one of the first signs that an episode is beginning. Relaxation techniques or prescription medications may be able to prevent this symptom in these cases. If the palpitations are accompanied by chest pain or difficulty breathing, a doctor should be consulted.
Caffeine or nicotine use can be potential causes of heart palpitations. This symptom is usually temporary and poses no significant health risks. If there are underlying health conditions, even those which have not yet been diagnosed, the use of these products could lead to moderate to severe health complications.
Hormonal changes are frequently causes of heart palpitations, particularly among women. Pregnancy, menstruation, and menopause lead to sometimes dramatic hormone fluctuations. While hormone-induced palpitations are not generally harmful, it is always wise to report any new symptoms to a doctor. Many doctors will choose to order a few diagnostic tests to make sure there are no major underlying medical issues before beginning a treatment program for hormonal disturbances.
Cardiac problems can be among the most serious causes of heart palpitations. Abnormal or irregular heart rhythms can lead to palpitations and may signify the presence of a severe medical condition. A routine physical examination can determine if the heart rate is abnormal and if further testing is necessary. In some cases, the patient may be referred to a cardiologist, a doctor who specializes in heart-related issues.
Thyroid dysfunction is among the possible causes of heart palpitations. The thyroid gland is responsible for producing essential hormones which are vital to the normal metabolic function of the body. In a condition known as hyperthyroidism, too many hormones are released at once, potentially leading to significant health problems. In fact, if this condition is left untreated for a prolonged period of time, potentially fatal complications may arise.
