The patient with atrial fibrillation.

Atrial fibrillation is a frequently encountered arrhythmia, particularly affecting the elderly. Patients at significant risk for stroke should be considered for anticoagulation with warfarin. Management of atrial fibrillation revolves around either controlling the ventricular rate response or trying to maintain sinus rhythm with either pharmacologic or nonpharmacologic therapies. There are many treatment options to consider, based upon the patient's expectations, symptoms, and comorbid conditions. Therefore, the treatment of atrial fibrillation must be individualized.
