May aid individualized LV and systemic hemodynamic assessment; leaves open prospective clinical validation.
A novel two-stage mathematical identification scheme allows for functional characterization of the hemodynamic properties of the left ventricle and systemic load in individual patients.
Clark et al. (1980) studied Patients undergoing cardiac catheterization. Two-stage sequential Prony-Marquardt technique was evaluated on Best fit of model-generated and observed aortic and brachial artery pressures. A two-stage sequential Prony-Marquardt technique successfully determines parameters of a modified Windkessel model to characterize the hemodynamic properties of the left ventricle and systemic load.
