测量左房室平面位移评价左室收缩功能与CK技术的比较

目的：探讨左房室平面位移（ＬＡＶＰＤ）在评价左室收缩功能中的价值。方法：研究对象为冠心病组３０例，正常对照组２０例。采用Ｍ超测量对应间壁、侧壁、下壁及前壁四个位点的ＬＡＶＰＤ，然后在２ＤＥ上测量左室ＥＦ值，并采用彩色室壁运动分析（ＣＫ）技术分析对应室壁的局部运动状况，加以记分。结果：１．冠心病组四个位点的ＬＡＶＰＤ均值与左一显著正相关，相关系数０．８７（Ｐ〈０．００１）。各个位点的ＬＡＶＰＤ测值均

Measurement of Left Atrioventricular Plane Displacement for Evaluating Left Ventricular Systolic Function:Comparison with Color Kinesis

Objective:To study the value of left atrioventricular plane displacement(LAVPD)for evaluating left ventricular systolic function.Methods:Thirty patients with coronary heart disease(CHD)and 20 healthy subjects were involved.The LAVPD was measured at four different sites corresponding to the septal,lateral,inferior and anterior wall by M mode.The left ventricular EF was measured at 2DE.The corresponding wall motion was analyzed and scored by color kinesis(CK)technology..Results:1 The mean LAVPD correlated linearly with LVEF in CHD patients( r =0 87, P <0 01).The LAVPD correlated negatively and linearly with corresponding wall motion score obtained by CK;2 All the CHD patients had a decreased LAVPD at all the sites compared to healthy subjects( P <0 05).The site corresponding to abnormal wall motion had a decreased LAVPD compared to the site corresponding to normal wall motion( P <0 05).Conclusions:The measurement of LAVPD can be used to evaluate the LV systolic function.
