Abstract：Objective To investigate clinical diagnosis value of dilated cardiomyopathy myocardial motion functions using two‐dimensional speckle tracking displacement imaging .Methods We quantitated longitudinal displacement and time to peak longitudinal displacement of left ventricular 17 segment through 45 normal persons and 32 patients with dilated car‐diomyopathy myocardial using GE Vivid E9 ultrasound unit and Echopac advanced workstation .Results LV longitudinal displacement was significantly decreasing from basal to apical segments in the normal group .The left ventricular segment displacement was greater in the normal group than DCM group with statistically significant difference .LV time to peak longitudinal displacement was located before AVC (aortic vavle colsed)in the normal group ,and after AVC in the DCM group;LV time to peak longitudinal displacement was more significantly delayed in the normal group than DCM group and there was a statistically significant difference between groups .Conclusion Two‐dimensional speckle tracking displacement imaging can provide new parameter for clinical evaluation of dilated cardiomyopathy myocardial motion functions .
