Contributions of heart movement and blood volume change to impedance cardiography calculated by human thorax models

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The contributions of the structural change, including the heart movement and bold volume changes of heart chambers and blood vessels, to impedance Cardiography were studied. A scheme was proposed to separate the heart movement and blood volume changes between end diastole and end systole using three dimensional (3D) human thorax models. Although the net impedance change due to the structural change was relatively small, the individual variation due to various factors was large with significant cancellation occurring. The results indicate that the thoracic impedance signal is a mixed representation of many inseparable factors and may not be reliable for the stroke volume (SV) calculation.
