Figure 5 Comparison of resting end-systolic pressure/volume ratio (Pes/Ves) as an estimate of elastance to directly measured left ventricular end-systolic elastance (Ees) by invasive analysis. Unlike Ees(sb) (Fig. 3B), the pressure-volume ratio consistently overestimated directly measured Ees, and the regression had a non-zero bias (2.2 mm Hg/ml) as demonstrated in the lower Bland-Altman plot.
