What are heart palpitations?

Heart palpitations are feelings that your heart races, jumps, throbs, or flutters. You may feel extra beats, no beats for a short time, or skipped beats. You may have these feelings in your chest, throat, or neck. They may happen when you are sitting, standing, or lying. Heart palpitations may be frightening, but are usually not caused by a serious problem.

What causes heart palpitations?

• Anxiety, stress, or lack of sleep
• Exercise
• A fever or illness
• Medicines, such as diet pills, certain cold and allergy medicines, and herbal supplements such as ginseng
• Caffeine, nicotine, or illegal drugs such as cocaine
• Pregnancy
• Medical conditions, such has dehydration, thyroid disease, low blood sugar level, or anemia

How are heart palpitations diagnosed?

Your healthcare provider will examine you and ask about your symptoms. Tell the provider if you smoke, use illegal drugs, or have a family history of heart problems. Rarely, heart palpitations may be caused by a more serious condition. Examples include a heart valve problem, heart failure, or a problem with how your heart beats. You may need tests to make sure your palpitations are not caused by a more serious problem:

• Blood and urine tests measure your electrolyte, blood cell, and blood sugar levels. Your thyroid hormone levels may also be measured. If you are a woman, your blood or urine may be tested for pregnancy hormones.
• An EKG test records your heart rhythm and how fast your heart beats. It is used to check for abnormal heart beats or heart damage. You may also need to wear a Holter monitor while you do your usual activities. A Holter monitor is a portable EKG that you may wear for 24 to 48 hours.
• An echocardiogram is a type of ultrasound. Sound waves are used to show the structure and function of your heart.
• An exercise stress test helps healthcare providers see how well your heart handles stress. The test can check for blockages in your heart or abnormal heartbeats. Ask your healthcare provider for more information about a stress test.
• An electrophysiology study is a procedure to check the electrical pathways in your heart. The electrical pathways control your heartbeat.

Palpitations usually do not need treatment. Your healthcare provider may stop or change your medicines if they are causing your palpitations. Conditions that cause palpitations, such as an abnormal heartbeat, will be treated.
