The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves. She presented to the emergency department after a couple of days of chest discomfort.

ABSTRACT Background Atrial fibrillation and atrial flutter are relatively rare in young people and the incidence of thromboembolic complications is unknown. Structural heart disease (SHD) was present in 120 patients (57%) and 20 patients (10%) had a primary cardiomyopathy.

The Differential Diagnosis is: SVT with aberrancy(#) [AVNRT vs. WPW (also called AVRT*)] Atrial flutter with 1:1 conduction, with aberrancy VT coming from the anterior fascicle ( fascicular VT )@ *AVRT = AV Reciprocating Tachycardia (Tachycardic loop that uses both the AV node and an accessory pathway.

The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. Patient course The patient was started on beta blockers and schedule for an electrophysiologic study. Biatrial enlargement, severe.
