OVERVIEW

What are heart palpitations?

 Heart palpitations are the sensation that your heart is pounding, racing, or skipping beats (fluttering). It is normal to hear or feel your heart “pounding” as it beats faster when you exercise. You may feel it when you do any physical activity. But if you have palpitations, you might feel your heart pounding while you are just sitting still or moving slowly.

SYMPTOMS

Heart palpitations may feel different to different people. They may feel like your heart is skipping a beat. They may feel like a flutter in your chest. Or they may feel like the pounding described above. You may have heart palpitations while you are sitting or while you are lying down.

CAUSES & RISK FACTORS

What causes heart palpitations?

Many things can cause palpitations. Some causes of heart palpitations include:

• Heart-related causes. People who have an irregular heartbeat or arrhythmia may have palpitations. (Arrhythmia is a change in the rhythm of your heartbeat.) Most of the time, palpitations and irregular heartbeats are harmless. However, sometimes the break in your heart’s normal rhythm can be a serious problem. You also may have palpitations if you have problems with the valves in your heart. Valves help move blood through the heart.
• Non-heart-related causes. Certain medicines, herbal supplements and illegal street drugs can make your heart beat faster. Medicines that can cause palpitations include asthma inhalers and decongestants. Caffeine (found in coffee, tea and soda), alcohol and tobacco can also cause palpitations. People who have panic disorder feel their heart pounding when they are fearful of something or having a panic attack. Some medical conditions, such as thyroid disease and anemia, also can cause palpitations.

Sometimes the cause of palpitations cannot be found. This happens in about 1 of every 7 people who have palpitations. Palpitations in these people usually harmless.

DIAGNOSIS & TESTS

Your healthcare provider will examine you and ask you about any medicines you are taking. They may ask about your diet and ask if you have panic attacks. Your healthcare provider may want you to have an electrocardiogram test. This test checks how your heartbeat over a certain period of time. Your healthcare provider also may test your blood.

If these tests do not show what is causing your palpitations, your healthcare provider may have you wear a heart monitor for 1 to 30 days. This monitor will show any breaks in your heart’s rhythm. Your healthcare provider might refer you to a cardiologist (a heart healthcare provider) for more tests or treatment.

PREVENTION

Can heart palpitations be prevented or avoided?

Heart palpitations cannot always be prevented or avoided. Here are some things you can do that may help prevent or avoid them:

• Do not use illegal street drugs, such as cocaine.
• Avoid caffeine, alcohol and tobacco.
• Tell your healthcare provider what medicines and herbal supplements you take.
• Tell your healthcare provider how much alcohol you drink, and if you use anything else that might cause palpitations.
• Keep track of your palpitations. Write down the time that they happen and what you were doing when they began. Give this information to your healthcare provider. They may be able to use this information to determine what is causing your heart palpitations.

TREATMENT

Most of the time, heart palpitations are harmless and will go away on their own. In these cases, they do not require treatment.

However, heart palpitations can sometimes be a sign of a more serious heart condition. If you have palpitations and are also dizzy or have shortness of breath, seek immediate medical attention.

If your heart palpitations are related to a heart condition or other medical problem, your healthcare provider will treat you for that. In these cases, your palpitations will likely go away as a result of treatment.

If your heart palpitations are a result of certain foods, beverages (alcohol and caffeine), or medications, try cutting back. Doing so could stop your palpitations.

Living with heart palpitations

If you can understand what is causing your palpitations, you will likely be able to manage them. You will be able to avoid known triggers, like diet pills, caffeine, and cold/cough medicines.

Palpitations that are caused by anxiety or stress are sometimes harder to control. The anxiety can cause the palpitations, and the palpitations can create anxiety. These often make up a seemingly endless cycle. In these cases, your healthcare provider may prescribe a medicine to ease your anxiety.
