Atrial flutter is a type of heartbeat problem (arrhythmia) that usually causes a fast heart rate. This fast rate is caused by changes in the electrical system of your heart.
Normally, the heart beats in a strong, steady rhythm. In atrial flutter, a problem with the heart's electrical system causes the two upper parts of the heart (the right atrium and the left atrium) to flutter, or beat very fast. Atrial flutter might be diagnosed using an an electrocardiogram (EKG). An EKG translates the heart's electrical activity into line tracings on paper.
This problem can be dangerous. If the heartbeat isn't strong and steady, blood can collect, or pool, in the atria. And pooled blood is more likely to form clots. Clots can travel to the brain, block blood flow, and cause a stroke. Over time, atrial flutter can also lead to heart failure.
Treatment for atrial flutter helps prevent stroke and heart failure. It also helps relieve symptoms.
Atrial flutter is often caused by another heart condition, such as coronary artery disease or another heart rhythm problem. It may happen after heart surgery.
Many people with atrial flutter are able to live full and active lives.
Some people have symptoms when they have episodes of atrial flutter. But other people don't notice any symptoms.
If you have symptoms, you may feel:
You may notice signs of atrial flutter when you check your pulse. Your pulse may seem fast.
Treatments can help you feel better and prevent future problems, especially stroke and heart failure.
The main types of treatment slow the heart rate and help prevent stroke. Your treatment will depend on the cause of your atrial flutter, your symptoms, and your risk for stroke. Treatments include:
You can live well and help manage atrial flutter by having a heart-healthy lifestyle.
