  • Abstract
    An elastance-resistance model of the left ventricle is used in conjunction with previously measured left ventricular pressure and outflow to derive elastances under three different loading conditions: control, hypertension, and hypotension. Using various times and time ratios of the elastance curves, it is shown that for decreasing load, elastance increases at a faster rate. This is also shown by normalizing the elastance curves with respect to the maximum elastance (E max) and the time to Emax. Possible explanations for these observations are given
