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.
Curative ablation: The most common type of atrial flutter, called typical atrial flutter, is responsible for the great majority of these abnormal heart rhythms. Typical atrial flutter is a circuit around the right atrium; the details of this circuit were first discovered and described by UCSF researchers. Ablation is a straightforward, highly successful, and low-risk procedure that can be employed to cure this rhythm.
