Arterio-ventricular coupling in pulmonary artery-banded and control animals subjected to incremental norepinephrine and dobutamine infusions. LV: left ventricle. RV: right ventricle. Ea: arterial elastance. ESPVR: end-systolic pressure volume relationship. *Significant difference between the effect of norepinephrine and dobutamine infusions in pulmonary artery-banded animals. Grey square: control. Black circle: pulmonary artery banding. Dotted lines indicate baseline 1 level. Data presented as mean (SD)
