以射频消融结果为依据，评定Ｓ＿２Ｒ跃增值和ＲＰ＿Ｅ时距对４８例慢－快型房室结折返性心动过速（Ｓ－Ｆ型ＡＶＮＲＴ）和１４１例顺向型房室折返性心动过速（Ｏ－ＡＶＲＴ）患者的诊断及鉴别诊断价值，并讨论两类心动过速食管调搏的定量判别标准。结果表明：（１）Ｓ＿２Ｒ跃增以≥６０ｍｓ诊断ＡＶＮＲＴ为宜，但有一定局限性，其敏感性、特异性、诊断价值分别为９１．６％、８５．８％、７２．８％。（２）ＲＰ＿Ｅ时距≤７０ｍｓ和＞７０ｍｓ分别对Ｓ－Ｆ型ＡＶＮＲＴ、Ｏ－ＡＶＲＴ的诊断及鉴别诊断价值较高。敏感性、特异性、诊断价值分别为９３．８％、１００％、１００％与１００％、９３．８％、９７．９％．（３）少数（１７％）右侧壁旁道逆传性心动过速ＲＰ＿Ｅ／Ｐ＿ＥＲ可＞１．０。（４）Ｓ－Ｆ型ＡＶＮＲＴ与Ｏ－ＡＶＲＴ的定量判别Ｓ＿２Ｒ跃增、ＲＰ＿Ｅ标准宜分别取≥６０ｍｓ、≤７０ｍｓ与＜６０ｍｓ、＞７０ｍｓ。
Based on the results of radiofrequency ablation, 48 cases of slow-fast atrioventricular nodal reentrant tachycardia (S-F AVNRT) and 141 cases of forward-type atrioventricular reentrant tachycardia (O-AVRT) in patients with diagnostic and differential diagnosis, and discuss the two types of quantitative evaluation criteria for tachycardia pacing. The results showed that: (1) S_2R jump ≥60ms to diagnose AVNRT is appropriate, but it has some limitations. The sensitivity, specificity and diagnostic value are 91.6%, 85.8% and 72.8% respectively. (2) The RP_E time interval of ≤70ms and> 70ms, respectively, the S-F-type AVNRT, O-AVRT diagnosis and differential diagnosis of higher value. Sensitivity, specificity and diagnostic value were 93.8%, 100%, 100% and 100%, 93.8% and 97.9% respectively. (3) A small number (17%) of the right side wall retrograde tachycardia RP_E / P_ER can be> 1.0. (4) S-F type AVNRT and O-AVRT quantitative determination of S_2R jumped, RP_E standard should be taken ≥ 60ms, ≤ 70ms and <60ms,> 70ms.
