Abstract：Objective: To explore the value of real-time three dimensional echocardiography(RT3DE), strain rate imaging(SRI) in ventricular wall motion analysis. Method: Sixty-two patients with heart attack symptoms and 30 healthy volunteers were enrolled in this study. The patients were divided into two groups, according to 2DE; T1 group were composed of individuals with normal wall motion in 2DE, and T2 group were composed of individuals with abnormal ventricular septum motion in 2DE. RT3DE, SRI were performed. Results: There were differences among Tmsv 6-SD, Tmsv 12-SD, Tmsv 16-SD, Tmsv 6-Dif and Tmsv 6-SD%, Tmsv 16-SD%, Tmsv 6-Dif% of T2 group and normal control group(P<0.05). End systolic EDV% of 17 segment in T2 group showed significant differences in basal inferoseptal, mid inferoseptal, mid anteroseptal compared with that of normal control. There is no difference between T1 group and T2 group. The analysis on strain rate showed that the peak value of basal, mid, apical ventricular septum of T2 group during systolic phase and early diastolic phase reduced obviously compared with that of control group. There was a decrease of peak value of basal ventricular septum in diastolic phase of T1 group compared with normal control. Conclusion: RT3DE and SRI have obvious superiority in wall motion assessment, which provide new methods of assessing abnormal wall motion more quickly, objectively and quantitatively.
