I48.4: Atypical atrial flutter

Atypical atrial flutter is a specific type of abnormal heart rhythm, or arrhythmia, which primarily affects the upper chambers, or atria, of the heart. During atypical atrial flutter, the electrical signals that control heartbeat become disordered, causing the heart to beat in a rapid, irregular pattern. This can often be felt as palpitations, a rapid heartbeat, or general discomfort in the chest area. As the heart is not beating effectively, there may also be symptoms such as tiredness, breathlessness, or reduced ability to exercise. Some people may not have any noticeable symptoms but could still be at an increased risk of developing complications. These complications can include a stroke or heart failure, which occur when the abnormal heart rhythm disrupts the normal flow of blood.
