Vector impedance cardiograms in horizontal lead configuration [VICG(H)] were recorded in 34 normal subjects, 18 patients with mitral stenosis, 9 patients with mitral regurgitation, 14 patients with aortic regurgitation and 13 patients with non- cyanotic septal disorders. Data in normal subjects revealed that most of the phase reversal points in VICG(H) waveform did not coincide with those of conventional impedance cardiogram. The shape of VICG(H) waveform and values of VICG indices were observed to be markedly affected in patients having significant alteration in the pulmonary circulation and the changes observed were specific of the type of the disorder. The results of the study suggested that right side of the heart had dominant contribution in generation of VICG(H) waveform.
对34名正常受试者、18名二尖瓣狭窄患者、9名二尖瓣反流患者、14名主动脉反流患者和13名非紫绀型间隔疾病患者记录了水平导联配置的矢量阻抗心动图[VICG(H)]。正常受试者的数据显示，VICG(H)波形中的大多数相位反转点与传统阻抗心动图的相位反转点不一致。观察到在肺循环有显著改变的患者中，VICG(H)波形的形状和VICG指数值受到明显影响，并且观察到的变化是特定于疾病类型的。研究结果表明，心脏右侧在VICG(H)波形的产生中起主要作用。
