title: [The present research situation of cause of formation of impedance cardiograph waveform].
abstract: This paper summarized the present research situation of cause of formation of impedance cardiograph waveform in two aspects of early and current research on it by the means of consulting a great deal of domestic and foreign data. The paper pointed out that a practicable way for correcting Kubicek theory and its physical model, making SV formula more accurate is to apply finite element technology to the research field under the guide of impedance cardiograph electric field theory. At the same time, the paper made preliminary introduction on the author's research work in the area.
