Fig. 1From: The right ventricle: interaction with the pulmonary circulationRight ventricular–pulmonary arterial coupling as described by the effects of changes in right ventricular (RV) end-systolic elastance (Ees), pulmonary arterial elastance (Ea) and RV end-diastolic volume on RV systolic pressure and stroke volume. a As Ea varies. b As Ees varies. c As end-diastolic volume variesBack to article page
