Modeling Ventricular Pumping From Muscle Contraction Dynamics

Mathematical models of the heart require dynamic constitutive relations for the underlying heart muscle. Lumped models of the left ventricle typically depend on a time-varying elastance, and those of muscle on the contractile element, both of which set heart muscle’s elastic properties. A different approach based on underlying muscle contraction mechanisms, and that embodies dynamic elastance, will be presented. This general method can be applied to description of the approximately 650 striated muscles in the human body.
