| 摘 要： | 目的探讨应用速度向量成像技术(VVI)评价正常人的左室舒张功能并确定其正常参考值范围。方法结合超声、NT-BNP、临床症状等指标筛选健康人97名,使用西门子公司的Acuson Sequoia C512超声心动仪,采用VVI测量静息状态下左室二尖瓣环水平6个壁:室间隔、侧壁、前壁、下壁、前间隔、后壁的心肌舒张早期速度(E),脱机后进入VVI工作站操作界面采用盲法对图像进行VVI分析并计算平均值Em,测出E/Em,对正常人群的参考值范围给出参考界定。结果 97例正常人E/Em的参考值范围(单侧界限取95%界限)为(1,22.935);男性、女性E/Em参考值范围分别为(1,22.300)和(1,24.766);50岁以下男性、女性E/Em参考值范围分别为(1,22.413)和(1,24.314);50岁以上男性、女性E/Em参考值范围分别为(1,15.410)和(1,24.870)。结论 VVI作为一种新的超声技术,是无创性评价左室舒张功能的好方法,为临床准确评价左室舒张功能提供了一种可靠手段。

| Abstract: | Objective To study value of velocity vector imaging(VVI) in assessment of normal left ventricular diastolic function and the corresponding reference values.Methods Ninety-seven healthy subjects were selected by combined clinical,ultrasound,and NT-proBNP examinations.Using a Siemens Acuson Sequoia C512 echocardiograph,VVI was adopted to examine the myocardial early diastolic velocity(E) of the septal,lateral,anterior,inferior,anterior septum,and posterior wall of the left ventricle at the level of mitral ann... |
