本文研究了由手术证实的３５６例选择性右室负荷过重型先心病儿童心电向量图。按病种共分９个类型。术前常规记录Ｆｒａｎｋ导联心电向量图。测量和统计了Ｆ、ＬＳ及Ｈ面ＱＲＳ环在各象限的面积比率，用本室相应年龄正常人心电向量图作对照组。进行了数理统计及诊断试验研究。结果表明：诊断先心病右室肥厚最有价值的指标是Ｈ２大于总面积１５％、Ｆ２大于总面积３０％及Ｆ１小于总面积５０％。用ＱＲＳ环面积法诊断右室肥厚的敏感性、特异性、准确性、阳性似然比及阳性诊断价值分别为６０．０％～８８．３％、９２．３％～９５．８％、９０．９％～９５．１％、８．７～２０．５及８９．７％～９５．５％。试验证明，ＱＲＳ环面积是诊断右室肥厚最简易而可靠的定量诊断方法。
In this paper, 356 cases of selective right ventricular hypertrophy of children confirmed by surgery cardiogram ECG. According to the disease is divided into 9 types. Preoperative routine recording Frank lead ECG vector diagram. Measurement and statistics of the F, LS and H surface QRS ring in the quadrant area ratio, with normal room age room corresponding ECG vector diagram for the control group. Conducted mathematical statistics and diagnostic tests. The results show that: the most valuable indicators of diagnosis of congenital right ventricular hypertrophy H2 is greater than the total area of 15%, F2 is greater than 30% of the total area and F1 less than 50% of the total area. The sensitivity, specificity, accuracy, positive likelihood ratio and positive diagnostic value of QRS annulus area in the diagnosis of right ventricular hypertrophy were 60.0% ~ 88.3%, 92.3% ~ 95.8%, 90 .9% ~ 95.1%, 8.7 ~ 20.5 and 89.7% ~ 95.5%. Experiments show that, QRS ring area is the most simple and reliable diagnosis of right ventricular hypertrophy quantitative diagnosis.
