A novel method for estimating the end-systolic pressure-volume relationship (ESPVR) is presented. The method provides for accurate estimation of the ESPVR from a single beat of the cardiac cycle. The method is based on normalized human time varying elastance curves [E N (t N )]. The ESPVR is estimated from one beat using PV data measured at normalized time t N and end-systole (t max ) to predict intercept: ##EQU1## and slope: E max (SB) =P(t max )/[V(t max )-V 0 (SB) ]. The present invention provides a method for ESPVR estimation which is non-invasive and particularly applicable for bedside applications. |
