Fig. 6.
Left panels: myocardial (panel a) and chamber (panel b) normal compliance curves of chronically instrumented pigs plotted against the ventricular passive filling pressure for both the right (dotted line) and the left (solid line, shaded) ventricle. Right panels: characteristic shapes of RV Pf–V relationships (panel c) and corresponding global curves of RV myocardial compliance (panel d) under hypovolemic conditions, and during surgically created subacute (2–5 wk) states of pressure overload, volume overload and RV free wall ischemia in chronically instrumented dogs; arrows identify the end-diastolic data points.
