Symptoms in patients with atrial flutter typically reflect decreased cardiac output as a result of the rapid ventricular rate. The most common symptom is palpitations. Other symptoms include fatigue, dyspnea, and chest pain. (See Presentation.) ECG is essential in making the diagnosis. Transthoracic echocardiography (TTE) is the preferred initial imaging modality for evaluating atrial flutter. (See Workup.)
