Diagnosis

For heart palpitations, your doctor will listen to your heart using a stethoscope. He or she is also likely to look for signs of medical conditions that can cause heart palpitations, such as a swollen thyroid gland.

If your doctor suspects your palpitations are caused by an arrhythmia or other heart condition, tests might include:

  • Electrocardiogram (ECG). In this noninvasive test, a technician places leads on your chest that record the electrical impulses that make your heart beat.

    An ECG can help your doctor detect irregularities in your heart's rhythm and structure that could cause palpitations. The test will be performed either while you rest or during exercise (stress electrocardiogram).

  • Holter monitoring. You wear this portable device to record a continuous ECG, usually for 24 to 72 hours, while you keep a diary of when you feel palpitations. Holter monitoring is used to detect heart palpitations that aren't found during a regular ECG exam.
  • Event recording. If you don't have irregular heart rhythms while you wear a Holter monitor or if the events occur less than once weekly, your doctor might recommend an event recorder.

    You wear an event recorder as much as possible throughout the day and push a button on a recording device to indicate when you have symptoms. The device records your heartbeat so that your doctor can assess the heart rhythm when you have symptoms. You might wear an event recorder for several weeks.

  • Echocardiogram. This noninvasive exam, which includes an ultrasound of your chest, shows detailed images of your heart's structure and function.

    Ultrasound waves are transmitted, and their echoes are recorded with a device called a transducer that's held outside your body. A computer uses the information from the transducer to create moving images on a video monitor.

Treatment

Unless your doctor finds that you have a heart condition, heart palpitations seldom require treatment. Instead, your doctor might recommend ways for you to avoid the triggers that cause your palpitations.

If your palpitations are caused by a condition, such as an arrhythmia, treatment will focus on correcting the condition.

Lifestyle and home remedies

The most appropriate way to treat palpitations at home is to avoid the triggers that cause your symptoms.

  • Reduce stress. Try relaxation techniques, such as meditation, yoga or deep breathing.
  • Avoid stimulants. Caffeine, nicotine, some cold medicines and energy drinks can make your heart beat quickly or irregularly.
  • Avoid illegal drugs. Certain drugs, such as cocaine and amphetamines, can bring on heart palpitations.

Preparing for your appointment

If you have heart palpitations with severe shortness of breath, chest pain or fainting, seek emergency medical attention. If your palpitations are brief and there are no other worrisome signs or symptoms, make an appointment to see your doctor. Your doctor can help you find out if your palpitations are harmless or a symptom of a more serious heart condition.

Here's some information to help you get ready for your appointment:

What you can do

When you make the appointment, ask if there's anything you need to do in advance, such as restrict your diet or fast.

Make a list of:

  • Your symptoms, including any that seem unrelated to heart palpitations, and when they began
  • Key personal information, including family history of heart disease, arrhythmias, stroke, high blood pressure or diabetes, as well as major stresses or recent changes in your life
  • All medications, vitamins and supplements you take, including doses
  • Questions to ask your doctor

Take a family member or friend along, if possible, to help you remember the information you're given.

For heart palpitations, basic questions to ask your doctor include:

  • What is likely causing my symptoms or condition?
  • What are other possible causes?
  • What should I do if my symptoms return?
  • What tests will I need?
  • Do I need treatment and, if so, what?
  • I have other health conditions. How can I best manage them together?
  • Are there restrictions I need to follow?
  • Should I see a specialist?
  • Do you have brochures or other printed material I can have? What websites do you recommend?

Don't hesitate to ask other questions.

What to expect from your doctor

Your doctor is likely to ask you questions, such as:

  • Have your symptoms been continuous or occasional?
  • Do your palpitations start and stop suddenly?
  • Does it seem like your palpitations have a pattern, such as occurring the same time every day or during a certain activity?
  • What, if anything, seems to improve your symptoms?
  • What, if anything, appears to worsen your symptoms?
  • Are you having other symptoms such as shortness of breath, chest pain, fainting, or dizziness when you have palpitations?
  • Have you ever had heart rhythm problems before, such as atrial fibrillation?

What you can do in the meantime

Before your appointment, you can try to improve your symptoms by avoiding activities or stresses that might cause your palpitations. Some common triggers include anxiety or panic attacks, drinking too much caffeine or alcohol, or taking some medications or supplements that contain stimulants, such as energy drinks or some cold medicines.
