The rhythm differential for narrow, regular, and tachycardic is sinus rhythm, SVT (encompassing AVNRT, AVRT, atrial tach, etc), and atrial flutter (another supraventricular rhythm which is usually considered separately from SVTs). Therefore this patient is either in some form of SVT or atrial flutter.

There is a large peaked P-wave in lead II (right atrial enlargement) There is left axis deviation consistent with left anterior fascicular block. There is no evidence of infarction or ischemia. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm.

The ECG was interpreted as showing atrial flutter with 2:1 conduction. Are you confident there is no ischemia? 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. Do you agree with this strategy?
