【摘要】：目的全方向M型超声(OME)心动图评价房颤患者左心耳功能的应用价值。方法应用全方向性M型超声及定量组织速度成像(QTVI)技术测量左心耳壁三个节段(间隔、侧壁、顶部)峰值运动速度(PV),应用二维超声心动图及频谱多普勒超声技术分别测量左心耳二维面积变化率(2D-FAC)、峰值排空速度(PEV),应用经食管实时三维超声心动图测量左心耳舒张末容积(3D-EDV)、左心耳排空分数(3D-EF)等技术作为评价左心耳功能的指标。结果与对照组比较,阵发性房颤组与持续性房颤组左心耳各壁运动速度、2D-FAC、PEV、3D-EF均降低,以持续性房颤组降低更为显著(P0.01),3D-EDV增大,以持续性房颤组增大更为显著(P0.01);相关分析显示OME与QTVI、3D-EF技术测值具有良好相关性(P0.01),相关系数分别为(r=0.94、0.83)。结论左心耳壁运动速度的变化能够反映房颤患者左心耳壁心肌受损程度,全方向M型超声可定量评估房颤患者左心耳功能。
[Abstract]:Objective to evaluate the value of omnidirectional M-mode echocardiography (OME) in evaluating left atrial appendage function in patients with atrial fibrillation. Methods all directional M-mode ultrasound and quantitative tissue velocity imaging (QTVI) were used to measure the three segments of the left atrial appendage wall (septum, lateral wall). The peak motion velocity (PV) of left atrial appendage (2D-FAC) and peak emptying velocity (PEV) were measured by two-dimensional echocardiography and spectral Doppler echocardiography, respectively. The left atrial auricle was measured by transesophageal real-time three-dimensional echocardiography. End diastolic volume (3D-EDV) and left atrial appendage emptying fraction (3D-EF) were used to evaluate left atrial appendage function. Results in the paroxysmal atrial fibrillation group and the persistent atrial fibrillation group, the velocity of left atrial appendage (2D-FACU) PEV 3D-EF decreased, especially in the persistent atrial fibrillation group (P0.01). The correlation analysis showed that OME had a good correlation with QTVI 3D-EF (P0.01), and the correlation coefficient was 0.94 卤0.83 respectively. Conclusion the changes of left atrial appendage wall motion velocity can reflect the degree of myocardial damage in patients with atrial fibrillation, and the left atrial appendage function can be quantitatively evaluated by omnidirectional M-mode ultrasound.
