title: Sinus tachycardia and J wave masquerading as atrial flutter.
abstract: The admission electrocardiogram (ECG) from a patient with severe heart failure was considered diagnostic of atrial flutter with 2:1 atrioventricular conduction. Slowing of the heart rate revealed sinus tachycardia with prominent 'J' waves that had been previously thought to be 'F' waves.
