【摘要】：目的：1、应用心房追踪技术(AVT)评价高血压心房颤动(HAF)和孤立性心房颤动(LAF)患者右心房整体结构及功能的变化。2、应用定量组织速度成像技术(quantitative tissue velocity imaging，QTVI)联合二尖瓣环收缩期位移（mitral annulardisplacement,，MAD）及三尖瓣环收缩期位移（tricuspid annular plane systolicexcursion, TAPSE）评价孤立性心房颤动(lone atrial fibrillation，LAF)患者左、右心室功能。 方法：1、实验组为60例心房颤动患者，包含LAF组36例，HAF组24例（左、右心室结构正常），对照组为30例健康成人，分别应用M型超声测量左心室常规参数；应用二维超声测量患者左、右心房常规参数；应用心房追踪技术测量右心房最大面积(RAAmax）、右心房最大容积(RAVmax)、右心房最小容积(RAVmin)，计算右心房排空分数(RAEF)，收缩期右心房充盈速率峰值(dv/dtS)、舒张早期右心房排空速率峰值(dv/dtE)。2、LAF组36例心房颤动患者（左、右心室结构正常），对照组为30例健康成人，应用M型超声测量左、右心室结构常规参数，MAD，，TAPSE；应用多普勒超声测定二、三尖瓣瓣口舒张期峰值血流速度E；应用QTVI测量左心室侧壁二尖瓣环处、右心室侧壁三尖瓣环处收缩期峰值速度Vs，舒张期峰值速度Ve，并计算E／Ve。 结果：1、与健康对照组相比，心房颤动组的RAD1、RAD2、RAAmax、RAVmax、RAVmin、dv/dtE、LAD1、LAD2、LAD3明显升高，RAEF、dv/dtS明显减低(P均0.05）,LVEDD、LVESD、RVEDD、IVSTd、LVPWTd、LVEF各组间差异无统计学意义(P均0.05)。与HAF组相比，LAF组RAD1、RAD2、RAAmax、RAVmax、RAVmin、dv/dtE明显升高，LAD1、LAD2、LAD3、RAEF、dv/dtS明显减低(P均0.05)。2、与对照组相比，LAF组左心室E、E／Ve升高，Ve、Vs、MAD减低(均为P0.05），LAF组右心室E、E／Ve升高，Ve、Vs、TAPSE值减低(均为P0.05），IVSTd、LVPWTd、LVEDD、LVESD、LVEF、RVD1、RVD2、RVD3、RVAW、RVEF各组间差异无统计学意义(均为P0.05)。 结论：1、LAF右心房结构和功能损害程度较HAF患者更为明显。2、LAF组在心室结构没发生改变前，左、右心室功能均已受损。
[Abstract]:Objective to evaluate the changes of global structure and function of right atrium in patients with hypertensive atrial fibrillation (Haff) and isolated atrial fibrillation (LAF) by using atrial tracing technique (AVT) and quantitative tissue velocity imagingQTVI (quantitative tissue velocity imaging) combined with mitral annulus (mitral annulus). Left and tricuspid annular plane systolicexcursion, TAPSEs were used to evaluate solitary atrial fibrillation (LAF) in patients with isolated atrial fibrillation. Right ventricular function. Methods Twenty six patients with atrial fibrillation in the experimental group, including 36 patients in the LAF group and 24 patients in the haf group (with normal left and right ventricular structure) and 30 healthy adults in the control group, were used to measure the normal parameters of left ventricle by M-mode ultrasound. The normal parameters of left and right atrium were measured by two-dimensional ultrasound. The maximum area of right atrium was measured by means of atrial tracing technique, and the maximal volume of right atrium was measured by RAVmax1, and the minimum volume of right atrium was measured by RAVmin. The right atrial emptying fraction was calculated, the peak filling rate of right atrium during systolic period was measured, and the peak value of ejection rate of right atrium in early diastolic stage was calculated. 36 patients with atrial fibrillation (left, left) The normal structure of the right ventricle was normal, the control group was 30 healthy adults, the normal parameters of left and right ventricular structure were measured by M-mode ultrasound, and the peak diastolic velocity of the second, tricuspid valve orifice was measured by Doppler ultrasound. The systolic and diastolic peak velocities of mitral annulus and tricuspid annulus were measured by QTVI, and E / V _ e was calculated. Results compared with the healthy control group, RAD1 / RAD2 / RAAMAXERVmax / RAVmint / dtE / LAD1 / dt2 / LAD3 in atrial fibrillation group was significantly higher than that in healthy control group (P < 0. 05). There was no significant difference between the two groups (P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05). 涓嶩AF缁勭浉姣
