A FEM has been used to examine influence of tissues' conductivities and electrodes' array configurations on the results obtained by Impedance Cardiography. A Geselowitz's relationship has been applied to estimate partial contributions from each region of thorax. The obtained results have indicated the strong dependence of ICG signal on factors mentioned above. It seems that additional measurements and more advanced ICG waveform processing must be done to minimise errors in estimating parameters of mechanical work of heart by means of ICG.
有限元模型已被用于研究组织电导率和电极阵列配置对阻抗心动图测量结果的影响。采用格塞尔洛维茨关系来估计胸部各区域的部分贡献。所得结果表明，阻抗心动图信号强烈依赖于上述因素。似乎必须进行额外的测量和更先进的阻抗心动图波形处理，以尽量减少通过阻抗心动图估计心脏机械功参数时的误差。
