A numerical simulation system for the estimation of mechanical properties and functions of the human left ventricle has been constructed in a interdisciplinary research between the medical and engineering fields. The numerical system can be expected to improve the diagnoses of heart diseases from empirical, subjective and qualitative ones to the scientific, objective and quantitative ones. The system is composed of four fundamental models: ( 1 ) a mechanical model of myocardiac muscle fiber which produces the active force, ( 2 ) a mechanical model of the left ventricle which is composed of the muscle fibers, ( 3 ) a transmission model of electric stimulus, and ( 4 ) a circulation model of blood which gives the after- and pre-loads to the model of the left ventricle. In this paper, the fundamental system of the simulator is explained, and some typical examples of computational results obtained by this system are shown and discussed.
