Studies analyzing the diagnostic value of 12-lead electrocardiographic criteria differentiating slow–fast atrioventricular nodal reentrant tachycardia (AVNRT) from atrioventricular reentrant tachycardia (AVRT) due to concealed accessory pathway have shown inconsistent results. In 97 patients (50 with AVNRT, 47 with AVRT) 12-lead electrocardiograms (ECGs) were recorded during sinus rhythm and tachycardia (QRS <120 ms). The ECGs were blinded for diagnosis and patient and analyzed independently by 2 electrophysiologists. The studied criteria differentiating AVNRT from AVRT included pseudo-r′/S, the presence of a retrograde P wave, RP interval, ST-segment depression ≥2 mm with the number and location of the affected leads, QRS amplitude, and cycle length alternans.
