Atrial flutter is an arrhythmia that occurs predominantly in patients with previous heart disease. This article reports the case of a patient with rheumatic heart disease and with two exchanged valves, the aortic and mitral, and the last exchange procedure took place ten years ago, with the placement of metallic prostheses. The first diagnosis was paroxysmal supraventricular tachycardia (PSVT) and it was attempted cardioversion with adenosine, without success. The electrocardiogram (ECG) was revised and atrial flutter was diagnosed. Electrical cardioversion was performed after 9 days in hospital, and the rhythm was sustained.
