摘    要:目的:应用定量组织速度图(TVI)对正常健康者左心室各节段运动速度进行检测,了解正常中、老年人心肌运动速度有无差异,确定左室壁各节段运动速度的正常值范围。对冠心病、心肌缺血进行定量检测、评价,探讨TVI技术在临床的应用价值。方法:应用TVI技术对50岁以上和50岁以下各30人进行左室壁速度检测,把两组进行显著性检验,对已确诊的45例(35例经冠状动脉造影)冠心病患者进行检测分析。结果:正常人左室壁各节段有一定的运动规律。健康人组50岁以上和50岁以下两组无显著性差异。冠心病组可检出运动异常节段,表现为速度的降低和波形的改变。结论:TVI可定量检测冠心病室壁运动异常,评价心肌缺血。长轴方向心底平均收缩速度<5cm/秒,乳头肌水平平均收缩速度<5cm/秒。可做为判断冠心病室壁运动异常的参考量化标准。

关 键 词:超声心动图  组织速度图  冠心病  诊断  室壁运动异常

Abstract:Objective:To determine the velocity of left ventricular movement in normal adults and know whether variances exist between the velocity of middle and old people.To quantitatively evalauate the velocity in coronary artery disease(CAD)and to explore the clinical application of tissue velocity imaging(TVI).Methods:Thirty normal cases over 50 years of age,30 normal cases under 50 years of age,and 45 cases Of CAD(35 of them have been confirmed by coronary angiography) were involved in the observation.The velocity of the left ventricular segmental movement was measured and analysed with TVI in all cases.Results:There were some regularities of the left ventricular segmental movement in normal cases.No difference was found between the two normal groups.The decrease of the velocity and the changes of its wave curve were shown in abnormal segmental movements in the CAD group.There were obvious differences between the velocity values of normal and abnormal segment.Conclusions:TVI can quantitatively measure the abnormal movement of ventricular wall and evaluate myocardial ischemia.It has showed that the velocity values of S<5 0cm/s in the basal segment in longitudinal axis and S<3 0cm/s of the papillary segment can be used as the criteria of abnormal regional wall movement.
Keywords:Echocardiography  Tissue velocity imaging  Coronary artery disease
