Chapter Summary

This chapter discusses the epidemiology, pathophysiology, and classification of atrial fibrillation (AF) and atrial flutter, as well as the clinical presentation, evaluation, and management of patients with these arrhythmias (see Fuster and Hurst’s Central Illustration). Patients may have a range of presentations from asymptomatic, with the arrhythmia detected only by electrocardiography or other monitoring, to highly symptomatic. Management approaches should be individualized to patient symptoms and comorbidities. Management of AF may require cardioversion acutely for symptomatic patients, followed by strategies to prevent recurrent AF and minimize sequelae such as stroke. An important consideration in the management of AF is lifestyle modification, because conditions such as sleep apnea, obesity, excessive alcohol intake, and lack of exercise may contribute to the development or maintenance of AF. Long-term management includes anticoagulation for the prevention of thromboembolism in patients deemed to be high risk. The other pillars of management of AF are rate control and rhythm control. Emerging data support early rhythm control by antiarrhythmic drugs or catheter ablation, especially in certain subpopulations such as those with concurrent heart failure. The management of atrial flutter is analogous in most respects to that of AF, although typical atrial flutter is curative in most cases with catheter ablation.

Atrial fibrillation (AF) is the most common sustained arrhythmia in the world, affecting at least 33 million individuals.1 This is likely an underestimate because it is expected to double over the next 40 years ...
