ABSTRACT
Objective To explore the value of quantitative tissue velocity imaging (QTVI) in quantitatively evaluating segmental systolic function of left ventricle. Methods Fifteen healthy volunteers(group A) and fifteen myocardial infarction patients (group B) were studied at apical four-chamber view, two-chamber view and apical longitudinal view using QTVI. Septal, lateral, anterior, inferior, ante-septal and posterior walls were divided into basal, middle and apical segments respectively, in total 18 segments. The systolic peak velocity (Vp), systolic peak displacement (D), systolic peak strain rate (SR) and strain (S) were measured respectively for each segment of both groups. Results For abnormal wall motion segments in group B, the value of Vp showed significant lower in 16(16/18) segments, D in 15(15/18) segments, SR in 17(17/18) segments and S in 16(16/18) segments than those in the corresponding segments of group A (all P
