Department of Cardiology, the First Affiliated Hospital of Lanzhou University, Lanzhou 730000, China [Abstract] Objective The purpose of this study was to analyze the consistency in evaluating global left ventricular systolic function(LVSF) in normal population by M-mode Teichholz methods ,Two-dimensional echocardiography（2DE）Simpson’s methodume (LVEDV),left ventricular end-systolic volume (LVESV),stroke volum (SV) and left ventricular ejection fraction (LVEF) were measured through M-mode Teichholz methods、2DE Simpson’s methods and RT-3PE. Results For the measurement of LVEDV、LVESV、SV and LVEF ,there was good correlation between RT-3PE and 2DE Simpson’s methods(r=0.9140.892,0.815,0.996),as well as between RT-3PE and M-mode Teichholz methods (r=0.896,0.814,0.796,0.917),Furthermore,there were no statistically significally difference among the values of LVEDV、LVESV、SV and LVEF measured by three ways. Bland-Altman analysis showed a good consistency between RT-3PE and 2DE Simpson’s than between RT-3PE and M-mode Teichholz methods in the measurement of SV and LVEF. There was a good correlation for interobs
