Nineteen planimetric indices of 110 cardiac healthy subjects, 141 patient with left ventricle loading and 136 patients with right ventricle loading are analyzed. On the base of the variation analysis and determination of statistically significant differences, it was established that in right-ventricular loading the following indices deviate from the norm: ASX, AQZ, AQRSX, AQRSz, SAQRSx, SAQRSy, SAQRSz, SAS, SAQRSg, whereas in left-ventricular loading -- ARx, ARz, AQRSx, AQRSz, SAQRx, SAQRSy, SAQRz, SAR, SAQRSg. At a second stage, the sensitivity of the separate indices from the groups with left ventricular and right-ventricular loading was amalyzed, as well as the separate subgroups (pulmonary stenosis, aortic stenosis, mitral stenosis, interauricular defect, arterial hypertension, mitral or aortic insufficiency. The results were compared with those of axial indices, obtained from another investigation of the authors. The planimetric analysis was established to be more complex than the axial and the index SAQRSg to be with the best sensitivity in the cases with hemodynamically lightly loaded musculature.
分析了110名心脏健康受试者、141名左心室负荷患者和136名右心室负荷患者的19个平面测量指标。基于变异分析和统计学显著差异的测定，确定在右心室负荷时，以下指标偏离正常：ASX、AQZ、AQRSX、AQRSz、SAQRSx、SAQRSy、SAQRSz、SAS、SAQRSg，而在左心室负荷时——ARx、ARz、AQRSx、AQRSz、SAQRx、SAQRSy、SAQRz、SAR、SAQRSg。在第二阶段，分析了左心室和右心室负荷组中各个指标的敏感性，以及各个亚组（肺动脉狭窄、主动脉狭窄、二尖瓣狭窄、房间隔缺损、动脉高血压、二尖瓣或主动脉瓣关闭不全）的敏感性。将结果与作者另一项研究中获得的轴向指标结果进行比较。平面测量分析被证明比轴向分析更复杂，并且指标SAQRSg在血流动力学负荷较轻的肌肉组织病例中具有最佳敏感性。
