Abstract :
A computer model-based approach is presented to characterize hemodynamic consequences of myocardial ischemia in terms of depressed ventricular elastance and delayed and reduced ischemic regional cardiac muscle shortening, as well as relaxation time constants. The model is shown to be versatile in quantifying the severity of myocardial ischemia.
