Abstract
Aortic wall stiffness plays a significant role in accelerating the risk of cardiovascular diseases and causes hemodynamic changes in the aorta. The aorta significantly contributes to the thoracic impedance measurements with impedance cardiography. In this study, a 3D finite element simulation model has been set up to investigate the impact of aortic wall stiffness on the morphology of the impedance cardiography signal. The results agree with experimental studies and show a possible reason for the inaccuracy of hemodynamic monitoring in older patients with impedance cardiography. [ABSTRACT FROM AUTHOR]
