What causes atrial flutter? Atrial flutter may be caused by abnormalities of the heart, by diseases of the heart, or by diseases elsewhere in the body that affect the heart. Atrial flutter may also be caused by consuming substances that change the way electrical impulses are transmitted through the heart. Atrial flutter can occur after open heart surgery.
This is an arrhythmia caused by one or more rapid circuits in the atrium. Atrial flutter is usually more organized and regular than atrial fibrillation. This arrhythmia occurs most often in people with heart disease and in the first week after heart surgery. It often converts to atrial fibrillation.
