Atrial flutter is much less common than atrial fibrillation. Of the patients admitted to US hospitals with a diagnosis of supraventricular tachycardia between 1985 and 1990, 77% had atrial fibrillation and 10% had atrial flutter. On the basis of a study of patients referred to tertiary care centers, the incidence of atrial flutter in the United States is estimated to be approximately 200,000 new cases per year. [5]
