Abnormal right ventricular function Elevated right ventricular systolic pressure 2020-09-03T12:08:23Z Elevation of right ventricular systolic pressure (RVSP) above normal limits. In adults, RVSP is normally 20-30 mmHg. In the absence of right ventricular (RV) outflow tract obstruction, RV systolic pressure is equal to pulmonary artery systolic pressure. The gold standard for the measurement of PH is right heart catheterization, but this is invasive with the inherent risk of complications. Echocardiography has been touted as providing an accurate measurement of the right ventricular systolic pressure based on the estimated flow of the tricuspid regurgitant jet.
