Figure 1 : 

Common parameters of right ventricular systolic function. Parameters commonly used for assessment of right ventricular systolic function are displayed in the panels A–E. A. Right ventricular ejection fraction (RVEF) using monoplane Simpson’s method as calculated by dividing the difference between the RV end-diastolic volume and the RV end-systolic volume by the RV end-diastolic volume in two-dimensional and apical four-chamber (A4C) view. B. S’ Tissue Doppler Imaging (TDI) to the tricuspid ring in lateral A4C window. C. Tricuspid annular plane systolic excursion (TAPSE) in lateral A4C view and M-mode. D. dP/dT in continuous Doppler in A4C at the level of Tricuspid Regurgitation (TR). E. Tei index (a–b)/a, in which a=(isovolumic contraction time+isovolumic relaxation time+ejection time) and b=ejection time.
