Here is the computer interpretation: ATRIAL FIBRILLATION WITH RAPID VENTRICULAR RESPONSE WITH ABERRANT CONDUCTION OR VENTRICULAR PREMATURE COMPLEXES LEFT AXIS DEVIATION [QRS AXIS beyone -30] NONSPECIFIC ST and T-WAVE ABNORMALITY The over-reading physician confirmed this diagnosis, which is incorrect. It is not atrial fibrillation.

The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. There are no P waves preceding the QRS complexes, and no clear flutter waves. But adenosine only lasts for seconds, and if the dysrhythmia recurs, then the adenosine is gone. Adenosine worked.

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?
