The authors made a quantitative and qualitative vectorcardiographic analysis (Frank lead system) in 47 patients with hypertensive heart disease compared with a control group of 16 normal subjects. The magnitude and the angle of the maximum QRS vector, the sense of rotation of the QRS loop, the magnitude of the maximum posterior deflection (Sz), of the anterior maximum one (Rz), of the maximum leftward one (Rx), and of the maximum rightward one (Qx), the length (L) and the width W) of the QRS loop, as well as the angle of the maximum T vector were measured. A significant difference, in all planes of the maximum QRS magnitude between the normals and the AHT was found, while the maximum QRS angle was not significantly different. The quantitative analysis of the veg made in the horizontal plane revealed significant differences for the Sz, Rx, L, and the relation Rz/Sz. The quantitative analysis made according to Varriale et al. (1966) revealed a prevalence of the cases of type I A (72.3%) and I B (21.3%).
作者对47例高血压性心脏病患者进行了定量和定性的向量心电图分析（Frank导联系统），并与16名正常受试者的对照组进行了比较。测量了最大QRS向量的大小和角度、QRS环的旋转方向、最大后向偏转（Sz）、最大前向偏转（Rz）、最大向左偏转（Rx）和最大向右偏转（Qx）的大小、QRS环的长度（L）和宽度（W）以及最大T向量的角度。在正常人和高血压心脏病患者之间，最大QRS大小的所有平面均存在显著差异，而最大QRS角度无显著差异。在水平面进行的向量定量分析显示，Sz、Rx、L以及Rz/Sz关系存在显著差异。根据Varriale等人（1966年）进行的定量分析显示，I A型（72.3%）和I B型（21.3%）病例占多数。
