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.

What is unusual about this arrhythmia? Doing so suggests that the R-R interval of this exceedingly rapid arrhythmia is just a tiny amount over 1 large box — which corresponds to a ventricular rate just under 300/minute ( ie, between 290-300/minute ). PEARL # 3: Atrial Flutter with 1:1 AV conduction is rare!

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.
