VCG data (McFee--Parungao system) were obtained from 12 patients with primary pulmonary hypertension (PPH). During 2 years, VCG investigations were repeated from 2 to 5 times. Various VCG-parameters were analyzed. Space and horizontal QRS areas, projection of integra QRS vector to axis y and the sum of Rx and Sx were diagnostically most significant. Their values proved abnormal at the beginning of survey. In the course of observation, states of the right heart chambers together with VCG-parameter dynamics were investigated in every patient. States of the right cardiac chambers improved in 4 patients. In all of them the parameter turned to normal values. In two patients, during the monitoring time monotonous increase of parameters was observed, with the state of the right heart chambers declining. In 6 patients, state of right heart chambers appeared relatively stable. In these patients, values of all the parameters were either stable or insignificantly changeable around some mean values. Thus, the dynamics of VCG-parameters makes it possible to estimate adequately the states of the right cardiac chambers in PPH patients. (Tab. 1, Fig. 4, Ref. 4)
从12例原发性肺动脉高压（PPH）患者获取了心向量图（VCG）数据（麦克菲-帕伦高系统）。在2年期间，VCG检查重复进行了2至5次。分析了各种VCG参数。空间和水平QRS面积、积分QRS向量在y轴上的投影以及Rx与Sx之和在诊断上最为重要。在调查开始时，它们的值被证明是异常的。在观察过程中，对每位患者右心腔状态以及VCG参数动态变化进行了研究。4例患者右心腔状态改善。在所有这些患者中，参数恢复到正常数值。2例患者在监测期间观察到参数单调增加，同时右心腔状态恶化。6例患者右心腔状态相对稳定。在这些患者中，所有参数的值要么稳定，要么围绕某些平均值有微小变化。因此，VCG参数的动态变化使得能够充分评估PPH患者右心腔的状态。（表1，图4，参考文献4）
