Background: There are many new methods for evaluating the left ventricular systolic function. The aim of this study was to compare the methods, which evaluate the systolic function such as M-modeTeichholz method, tissue Doppler imaging with Sm wave. Methods: 65 patients hospitalized with hypertension and dilated cardiomyopathy. All patients underwent echocardiographic examination by M-mode, two- dimensional, Doppler and tissue Doppler Imaging. Results:When left ventricular ejection fraction (EF) reduced, TDI with Sm velocity were also lower (p<0.001). When lateral Sm of mitral valve ring were > 7.7 cm/s and septal Sm mitral valve ring were > 6cm/s, EF ≥ 50% with the sensitivity 96,2% and the specificity 89.7%. Conclusions: Sm wave velocity may be used reliably to assess the left ventricular performance regardless of the patient’s echogenity. Key words: Tisue Doppler, Systolic left ventricular function
