Patients who are hemodynamically unstable, who have severe dyspnea or chest pain with AF, or who have preexcited AF should undergo urgent cardioversion. [71] In stable patients with symptomatic new-onset AF, the rate-control strategy may be considered first to control the ventricular rate. If rate-control treatment does not elicit a response or if echocardiography does not reveal any valvular or functional abnormality of the heart, cardioversion is indicated.
