Abstract

Chronic heart failure is a serious disease in our society which can potentially be diagnosed by impedance cardiography (ICG). However, there is a strong debate about using this technology. In this work, the capability of a simple model to generate the ICG signal by taking the aorta as major signal source has been analyzed. Therefore, a simulation with a high temporal resolution has been conducted using the finite integration technique (FIT). It has been shown that although neglecting other physiologic signal sources, the results obtained from the simulations produce an ICG signal which correlates very well with measured ICG signals.
