Abstract Background Right ventricular (RV) fractional area change and tricuspid annular plane systolic excursion (TAPSE) are recognised methods for assessing RV function. However, the way in which these variables affected by varying degrees of pulmonary hypertension (PH) has not been well characterised. Methods end-systolic (RVESA), end-diastolic (RVEDA), artery pressure (PASP) TAPSE were collected from a database 190 patients who had referred to PH clinic evaluation. Results The mean (SD) age study population was 56 (17) years; 82 men included with PASP 54 (33) mm Hg (range 16–150), RVESA 14 (9) cm2, RVEDA 24 44 (18)% 2.06 (0.69) cm. Receiver-operating characteristic curves identified <2.01 cm, <40.9%, >12.3 cm2 >23.4 as abnormal values PH. Finally stratification into sub-groups according their allowed means standard deviations be reported each echocardiographic variable. Conclusion This analysis provides range normal size function, previously published, that can used routine evaluation follow-up
