Objective To observe the velocity of left ventricular wall motion features of normal subjects and patients with abnormal regional wall movement of left ventricle with the quantitative tissue velocity imaging(QTVI),and to know whether variances exit between the velocity of left ventricular myocardial motion of the normal subjects and the abnormal subjects with coronary artery disease(CAD) and myocardial ischemia. The practical value of QTVI on myocardium movement of left ventricle was evaluated. Methods The segmental left ventricular wall motion velocity was measured on 27 normal subjects and 21 patients with CAD and myocardial ischemia,including three waves,peak velocity of systolic S wave,diastolic E wave,A wave, and time velocity integrate of S wave(S TVI) was used as measurement parameters.The parameters were analysed between the two groups. Results The velocity and S TVI were gradually decreased from base to apex in the same wall in the control group.There were some abnormal segmental movements in the abnormal group. S wave ,E wave and S TVI of diseased segments in the abnormal group were much lower than those of control group ( P  0.05 ). Conclusions QTVI can quantitatively measure the velocity in abnormal movement segment of ventrical wall of patients with CAD and myocardial ischemia.S wave,E wave and S TVI are better parameters of assessing systolic function of left ventricle.QTVI has clinical application in regional myocardial motion function evaluation.
