Atrial Flutter Overview. Atrial flutter is an abnormality of the heart rhythm, resulting in a rapid and sometimes irregular heartbeat. Such abnormalities, whether in the rate or regularity of the heartbeat, are known as arrhythmias. The beating of the heart is controlled by electrical impulses.
Treatment.

Drugs to prevent the formation of clots and emboli (anticoagulants or aspirin) are usually given.
