Heart rate (HR), right ventricle ejection fraction (RV EF), right ventricle end diastolic volume (RV EDV), right ventricle cardiac output (RV CO), mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR), diastolic pulmonary arterial pressure (dPAP), systolic pulmonary arterial pressure (sPAP). Intraobserver and interobserver reliability is assessed by the intraclass correlation coefficient (ICC). ICC values significantly different from zero (p<0.05) are denoted by *.
