Atrial Flutter

Atrial flutter means that your upper heart chambers (atria) are  beating very fast. It is caused by a problem in the electrical pathways of the heart muscle. It can be a sign of heart disease or other health problems that affect your heart.

Palpitations are the most common symptom of atrial flutter. This is the feeling that your heart is fluttering or beating fast or hard. When your heart beats too fast, it doesn’t pump blood very well. This can cause other symptoms. These include:

  • Anxiety

  • Tiredness (fatigue)

  • Shortness of breath

  • Chest pain

  • Dizziness

  • Fainting

Some people have no symptoms while they are in atrial flutter.

If this is the first time you’ve had atrial flutter, and you don’t have heart or lung disease, it may never happen again. But in most cases, atrial flutter comes and goes. It can last from a few hours to a couple of days. Sometimes the atrial flutter doesn’t ever go away. This is chronic atrial flutter.

Atrial flutter may be caused by heart disease. It may also be caused by other conditions that affect the heart:

  • Coronary artery disease (arteriosclerosis). This is also sometimes called blocked arteries.

  • High blood pressure

  • Disease of the heart valves

  • Enlarged heart

  • Heart failure

Atrial flutter can occur without heart disease. This may be because of:

  • Overactive thyroid (hyperthyroid)

  • Chronic lung disease (COPD, emphysema, or bronchitis)

  • Alcohol use

  • Drugs or medicines that stimulate the heart. These include cocaine, amphetamines, diet pills, some decongestant cold medicines, caffeine, and nicotine.

  • Infection

  • Obesity

  • Sleep apnea

Treating or removing these causes will make it more likely that treatment for atrial flutter will work. It will also make it less likely that atrial flutter will come back.

Atrial flutter can happen along with another heart rhythm problem called atrial fibrillation. The risk for stroke is higher with these conditions. Getting treatment can reduce your risk.

Home care

Follow these guidelines when caring for yourself at home:

  • Go back to your usual activities as soon as you feel back to normal.

  • If you smoke, stop smoking. Talk with your healthcare provider or call a local stop-smoking program for help.

  • Don’t take drugs or medicines that stimulate your heart. These include cocaine, amphetamines, diet pills, some decongestant cold medicines, caffeine, and nicotine.

  • Your provider may have prescribed medicine to stop atrial flutter from coming back. Take this medicine exactly as directed. Some medicines must be taken every day to work as they should. They aren't taken just when you have symptoms.

  • Your provider may also have prescribed a blood-thinning medicine called warfarin. This lowers your risk for stroke. Have your blood tested regularly as advised by your healthcare provider. This will help make sure the dose is right for you. Other blood thinning medicines don't need regular testing.

Follow-up care

Follow up with your healthcare provider, or as advised.

When to seek medical advice
