Figures

Figure 1
Figure 1
Effects of increased contractility on (A) the left atrial pressure-stroke volume relationship and (B) the aortic systolic pressure-stroke volume relationship. An increase in contractility shifts these relationships up (arrows), while decrease in contractility shifts these relationships in the opposite direction.
Figure 2
Figure 2
Pressure-volume loops in series (A) under varying aortic systolic pressures. The slope of the relationship between end-systolic points (red dots) defines ventricular elastance (Ees), while end-systolic pressure/stroke volume (SV) defines arterial elastance (Ea). Pressure-volume loops (B) before (solid blue) and after (dashed red) an acute increase in contractility resulting in increased ventricular elastance (Ees’).
