Conference paper


Atrial flutter (AFL) is a generic term for rapid macroreentrant atrial arrhythmias, presenting a surface ECG with little or no isoelectric interval between flutter waves. Originally, AFL was described as a macroreentrant arrhythmia which propagated in a counterclockwise direction around the tricuspid annulus (when viewed in the left anterior oblique projection). However, with the discovery of new forms of AFL and curative ablative techniques, terminology has become ever-important in the description and definition of these arrhythmias. The goal of this chapter is to establish a systematic approach to recognizing the various forms of AFL, with an emphasis on the role of ablation therapy.
