Atrial flutter is a type of abnormal heartbeat (arrhythmia). Normally, the heart beats in a steady rhythm. In atrial flutter, a problem with the heart's electrical system causes the upper parts of the heart (atria) to beat very fast, or flutter.
An episode of atrial flutter is not typically dangerous. But atrial flutter can lead to serious problems. During an episode, 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.
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.
The doctor will ask questions about your symptoms and past health and will do a physical exam. You will have an electrocardiogram (EKG or ECG). This test checks for problems with the heart's electrical activity. You may also have other tests to check the health of your heart.
Treatments can help you feel better and prevent future problems, especially stroke and heart failure.
The main types of treatment slow the heart rate, stop atrial flutter, and help prevent stroke. Your treatment may depend on the cause of your atrial flutter, your symptoms, your risk for stroke, and your preferences. Treatment options include:
