Abstract
Atrial flutter shares many characteristics with atrial fibrillation, but it is important to distinguish between these arrhythmias because of the varying underlying electrophysiology and response to therapy.
Key Points
- Although electrophysiologically different from atrial fibrillation (AF), atrial flutter (AFL) shares many characteristics, especially in terms of its pharmacological medical management.
- AFL can be classified as ‘typical’ or ‘atypical’ based on its anatomical and electrophysiological characteristics.
- Treatment of AFL focuses on identifying and treating reversible causes, controlling the ventricular rate and/or achieving sinus rhythm as well as reducing the risk of systemic embolisation.
- Radiofrequency ablation is generally regarded as a first-line therapy for typical flutter.
