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.

A deep neural network for 12-lead electrocardiogram interpretation outperforms a conventional algorithm, and its physician over-read, in the diagnosis of atrial fibrillation. IJC Heart and Vasculature 25(2019). How can you avoid overlooking this arrhythmia?

Atrial flutter with 2:1 conduction. The atrial flutter rate is approximately 200 bpm, with 2:1 AV conduction resulting in ventricular rate almost exactly 100 bpm. Further history revealed she had new onset atrial flutter soon after her aortic surgery, and was put on flecainide approximately 1 month ago.

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?
