摘　　要：目的　探讨经食管超声检测房间隔厚度及血流动力学意义。方法　使用经食管超声心动图及自动边缘检测技术对 83例窦性心律者的房间隔及左心房指标进行检测。结果　不同疾病的房间隔厚度、房间隔增厚分数存在差异 ,且左心房内径与心房收缩期房间隔厚度呈负相关 (r =-0 .60 18,P <0 .0 1) ,左心房容积变化率与房间隔增厚分数呈正相关 (r =0 .63 78,P <0 .0 1)。结论　房间隔厚度及变化能较好地反映左心房的血流动力学改变。Objective To investigate relationship between atrial septal thickness and atrial function by transesophageal echocardiography(TEE). Methods TEE and automatic bound detection (ABD) were performed in 83 consecutive sinus rhythm subjects including four groups: control group, nonrheumatic heart disease group, rheumatic mild mitral stenosis group and rheumatic severe mitral stenosis group. Results Atrial septal thickness(AST)and atrial septal thickness fraction (ASTF) were different in various heart diseases. There was high correlation respectively between left atrial diameter(LAD) and AST(r= -0.601 8 ,P< 0.01 ). There was high correlation between left atrial volume change fraction(LAVCF) and ASTF(r= 0.639 8 ,P< 0.01 ). Conclusions The measurements of AST and ASTF provide a new approach for left atrial function.
