THE THEORETICAL MODEL ABOUT THE ELASTIC CAVITY-BOUNDARYVALUE PROBLEM OF IMPEDANCE CARDIOGRAPHY
心阻抗图的弹性腔-边值问题理论模型

Five main reasons that lead to the larger differences between Nyboer-Kubicek formula and results of the more reliable clinical measurement methods were analysed. For the former three reasons the original physical model was modified. A new theoretical model of impedance cardiography was proposed accoding to the elastic cavity structure and the method solving boundary value problem. Finally, the new theoretical model was discussed preliminarily.
