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.
分析12导联心电图标准对鉴别慢快型房室结折返性心动过速（AVNRT）与隐匿性旁路所致房室折返性心动过速（AVRT）诊断价值的研究结果并不一致。对97例患者（50例AVNRT，47例AVRT）在窦性心律和心动过速（QRS<120ms）时记录12导联心电图（ECG）。心电图诊断及患者信息均保密，由2名电生理学家独立分析。用于鉴别AVNRT与AVRT的研究标准包括假性r'/S、逆行P波的存在、RP间期、ST段压低≥2mm以及受累导联的数量和位置、QRS波振幅和周期长度交替。
