Diagnostic Considerations

Atrial flutter must be differentiated from atrial fibrillation and chaotic atrial tachycardia. When atrial flutter is conducted to the ventricle in a 1:1 fashion, the electrocardiogram may resemble ventricular tachycardia. In patients with a 2:1 conduction ratio, the electrocardiographic findings often suggest a mild sinus tachycardia with first-degree atrioventricular block.
