【摘要】：目的：1、應用心房追蹤技術(shù)(AVT)評價高血壓心房顫動(HAF)和孤立性心房顫動(LAF)患者右心房整體結(jié)構(gòu)及功能的變化。2、應用定量組織速度成像技術(shù)(quantitative tissue velocity imaging，QTVI)聯(lián)合二尖瓣環(huán)收縮期位移（mitral annulardisplacement,，MAD）及三尖瓣環(huán)收縮期位移（tricuspid annular plane systolicexcursion, TAPSE）評價孤立性心房顫動(lone atrial fibrillation，LAF)患者左、右心室功能。 方法：1、實驗組為60例心房顫動患者，包含LAF組36例，HAF組24例（左、右心室結(jié)構(gòu)正常），對照組為30例健康成人，分別應用M型超聲測量左心室常規(guī)參數(shù)；應用二維超聲測量患者左、右心房常規(guī)參數(shù)；應用心房追蹤技術(shù)測量右心房最大面積(RAAmax）、右心房最大容積(RAVmax)、右心房最小容積(RAVmin)，計算右心房排空分數(shù)(RAEF)，收縮期右心房充盈速率峰值(dv/dtS)、舒張早期右心房排空速率峰值(dv/dtE)。2、LAF組36例心房顫動患者（左、右心室結(jié)構(gòu)正常），對照組為30例健康成人，應用M型超聲測量左、右心室結(jié)構(gòu)常規(guī)參數(shù)，MAD，，TAPSE；應用多普勒超聲測定二、三尖瓣瓣口舒張期峰值血流速度E；應用QTVI測量左心室側(cè)壁二尖瓣環(huán)處、右心室側(cè)壁三尖瓣環(huán)處收縮期峰值速度Vs，舒張期峰值速度Ve，并計算E／Ve。 結(jié)果：1、與健康對照組相比，心房顫動組的RAD1、RAD2、RAAmax、RAVmax、RAVmin、dv/dtE、LAD1、LAD2、LAD3明顯升高，RAEF、dv/dtS明顯減低(P均0.05）,LVEDD、LVESD、RVEDD、IVSTd、LVPWTd、LVEF各組間差異無統(tǒng)計學意義(P均0.05)。與HAF組相比，LAF組RAD1、RAD2、RAAmax、RAVmax、RAVmin、dv/dtE明顯升高，LAD1、LAD2、LAD3、RAEF、dv/dtS明顯減低(P均0.05)。2、與對照組相比，LAF組左心室E、E／Ve升高，Ve、Vs、MAD減低(均為P0.05），LAF組右心室E、E／Ve升高，Ve、Vs、TAPSE值減低(均為P0.05），IVSTd、LVPWTd、LVEDD、LVESD、LVEF、RVD1、RVD2、RVD3、RVAW、RVEF各組間差異無統(tǒng)計學意義(均為P0.05)。 結(jié)論：1、LAF右心房結(jié)構(gòu)和功能損害程度較HAF患者更為明顯。2、LAF組在心室結(jié)構(gòu)沒發(fā)生改變前，左、右心室功能均已受損。
[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緇勭浉姣
