Abstract：Objective To analyze features of left ventricle wall motion with tissue doppler imaging technique.Methods Under quiescent condition,2-dimensional color tissue Droppler images of standardized two-chamber、four-chamber and long-axis view of cardiac apex were taken.Contraction and diastolic velocity of basal section、middle section 、apical section of every ventricle wall in left ventricle were recorded.Results 1.The speed of different fractions in the same left heart ventricle wall of health adults were consistent: basilar part ＞ intermedius ＞ apex of heart.2.The speed of lateral wall is the highest and enterior septum is the lowest.Conclusion Tissue Droppler,especially tissue speed imaging,can be used to quantatively and objectively evaluate left ventricle wall motion.
