摘　　要：为探讨组织多普勒成像技术 ( TDI)评价左室舒张功能的价值 ,将 5 7例左室舒张功能减退患者分为三组。应用 TDI测定其二尖瓣环运动速度 ;脉冲多普勒技术测定其二尖瓣口和肺静脉血流频谱 ,并与 32例健康志愿者 (对照组 )比较。结果舒张早期心肌运动峰值速度在对照组、左室心肌松弛性减低组 ( 16例 )、左室充盈假性正常化组 ( 2 7例 )和限制性充盈组 ( 14例 )分别为 ( 12 .0± 3.6 ) cm/ s、( 7.9± 2 .3) cm/ s、( 7.6± 2 .2 ) cm/ s和 ( 7.5±3.1) cm / s;对照组与其他三组比较 ,P值均 <0 .0 0 1。认为To investigate the usefulness of tissue Doppler imaging in assessing the left ventricular diastolic function.In 57 patients with various stages of diastolic dysfunction and 32 normal volunteers the mitral annular motion was measured by tissue doppler imaging,the transmitral flow and pulmonary venous flow were recorded by pulsed Doppler echocardiography.In the groups of normal status,delayed left ventricular relaxation,pseudonormal left ventricular filling and restrictive left ventricular filing,the early diastolic peak myocardial velocity was (15.1±3.6)cm/s,(7.9±2.3)cm/s,(7.6±2.2)cm/s and (7.5±3.1)cm/s,respectively,which were significantly different(F=46.1,P<0.001).In conclusion,early diastolic peak myocardial velocity measured by tissue Doppler imaging is of great value in assessing the left ventricular diastolic function.
