In almost 200 case of left ventricular hypertrophy (LVH) secondary to hypertension (HT), including 75 cases with conduction disorders, 100 cases of normal adults and 20 cases of normal children, segmental (initial horizontal vector, maximal anterior and posterior vector of the QRS) and spatial vectorial parameters were correlated to segmental echocardiographic parameters (septum, anterior and posterior wall of the left ventricle) and mass parameters (left ventricular mass index). The only significant quantitative variables in hypertensive LVH are: on electrocardiography: the AQRS and Sokolow's index: on vectocardiography: the spatial vector: its magnitude, azimuth and elevation, the maximal posterior vector: its amplitude, the maximal anterior vector: its amplitude, the maximal width of the QRS azimuth of the efferent limb of the QRS, the ventricular gradient in the horizontal, frontal and sagittal planes; on echocardiography: the left ventricular mass index, the diastolic thickness of the septum and the VMNES, the diastolic thickness of the posterior wall of the left ventricle and its percentage thickening. The only significant correlations were observed between: the maximal posterior vector of QRS and the diastolic thickness of the posterior wall of the left ventricle: 0.01 < alpha < 0.02; the spatial vector and the left ventricular mass index: 0.01 < alpha < 0.001. The presence of a conduction disorder does not modify these last two qualitative variables but alters their correlation.
在近200例继发于高血压（HT）的左心室肥厚（LVH）病例中，包括75例有传导障碍的病例、100例正常成年人和20例正常儿童，节段性（QRS波的初始水平向量、最大前后向量）和空间向量参数与节段性超声心动图参数（室间隔、左心室前壁和后壁）及质量参数（左心室质量指数）相关。高血压性左心室肥厚中唯一显著的定量变量为：在心电图方面：AQRS和索科洛夫指数；在向量心电图方面：空间向量及其大小、方位和仰角、最大后向量及其幅度、最大前向量及其幅度、QRS波传出支QRS方位的最大宽度、水平、额面和矢状面的心室梯度；在超声心动图方面：左心室质量指数、室间隔舒张期厚度和VMNES、左心室后壁舒张期厚度及其增厚百分比。仅在以下两者之间观察到显著相关性：QRS波的最大后向量与左心室后壁舒张期厚度：0.01＜α＜0.02；空间向量与左心室质量指数：0.01＜α＜0.001。传导障碍的存在并不改变这最后两个定性变量，但会改变它们之间的相关性。
