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. If so, why?

Instead, the rate of 150, plus the history of AF, suggested atrial flutter. A close inspection of lead II showed P or flutter waves at a rate of about 300 bpm, also supporting atrial flutter. There appear to be flutter waves at a rate of 300. Flecainide encourages new atrial flutter.

Is there proof for this, or just an academic gossip? We know atrial flutters can be confined to one atrium. Pierre Jaïs Circulation 2000 ) When such flutters transform into fibrillation, how does the spillover of signals occur to the contralateral atrium? RA fib-rate can be more than LA, and vice versa.)
