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.

PEARL # 3: Atrial Flutter with 1:1 AV conduction is rare! Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.

PurposeAtrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment. A total of 78.6% No postoperative complications occurred in any patient.
