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.

There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. There are clearly no flutter waves, so it is not atrial flutter (a "macro-reentrant" atrial tachycardia) Is it AVNRT originating at the superior pole of the AV node, resulting in a retrograde P-wave before the QRS?
