THE DYNAMIC COUPLING OF LEFT VENTRICLE

Cardiovascular system is a complex interactive system. The study of ven- triculo-arterial coupling can be greatly helpful to reveal the mechanism and regularity of cardiovascular system diseases. The dynamic process of'the ventriculo-arterial coupling is considered "making use of E ( t ) -R model for the left ventricle and T-Y tube model for the arterial tree. The predicted pressure and flow waveforms agree well with the experimental data. The effects of the SA and LV properties on the LV/ SA function and the optimal coupling c~y? ventriculo-arterial are also discussed. The re- sults have clinical significance.
