This is a research in Kubicek electrode configurations for cardiac stroke volume calculation from the angle of Kubicek model simulation by 3-dimensional finite element method. In the process of computer simulation, we have studied, respectively, the effect of the width, thickness, and material property (specific resistance) of potential electrode band on cardiac stroke volume calculation in order to guide the choice of electrode configurations in the clinic. The simulation results showed that in Kubicek electrode configurations, its all properties of the potential electrode band affected the impedance results for cardiac stroke volume calculation, one main factor of which is the choice of the material property. Therefore, we have to attend to the choice of Kubicek electrode configurations while calculating SV by Kubicek method in order to improve the accuracy of SV calculation.
