Abstract :
Computer software for the IBM PC was developed to assess the contractile properties of the right and left ventricles simultaneously. Four indices of systolic function were computed from pressure and volume data. These four indices consist of the slopes and x intercepts of lines fitted to different aspects of the pressure-volume relationship. A shell-subtraction model was utilized to compute the dynamic right and left ventricular volumes from sonometric dimensions. The visual display of pressure-volume loops was emphasized to assist in the data analysis
