目的 应用组织多普勒检测三尖瓣环处心肌的运动特点，并与三尖瓣口血流频谱对比评价原发性高血压患者右室舒张功能。方法 依据Gannu分类方法将124例原发性高血压患者分组：正常左室构型组32例为Ⅰ组，向心性构型组30例为Ⅱ组，向心性肥厚组32例为Ⅲ组，离心性肥厚组30例为Ⅳ组，另选取健康查体者35例为对照组。应用脉冲多普勒(PW)测量三尖瓣口血流速度参数，心室充盈早期峰值E峰和心房收缩期峰值A峰，计算E/A比值；组织多普勒技术测量三尖瓣隔叶及前叶瓣环处的舒张早期运动速度(Em)、舒张晚期运动速度(Am)，计算Em/Am值。并对两种检测方法和各组测值进行比较。结果 原发性高血压Ⅲ组、Ⅳ组三尖瓣血流频谱A值增大，E/A ＜1，与对照组及高血压Ⅰ组、Ⅱ组比较，差异有统计学意义(P＜0.05)。原发性高血压各组Em/Am均＜1；不同组间Em/Am比较，差异有统计学意义(P＜0.05)。结论 组织多普勒显像比脉冲多普勒更早、更敏感地发现原发性高血压导致的右室舒张功能受损，且随着左心室室构的不同，右室舒张功能减退的程度有所差别。
目的 應用組織多普勒檢測三尖瓣環處心肌的運動特點，併與三尖瓣口血流頻譜對比評價原髮性高血壓患者右室舒張功能。方法 依據Gannu分類方法將124例原髮性高血壓患者分組：正常左室構型組32例為Ⅰ組，嚮心性構型組30例為Ⅱ組，嚮心性肥厚組32例為Ⅲ組，離心性肥厚組30例為Ⅳ組，另選取健康查體者35例為對照組。應用脈遲多普勒(PW)測量三尖瓣口血流速度參數，心室充盈早期峰值E峰和心房收縮期峰值A峰，計算E/A比值；組織多普勒技術測量三尖瓣隔葉及前葉瓣環處的舒張早期運動速度(Em)、舒張晚期運動速度(Am)，計算Em/Am值。併對兩種檢測方法和各組測值進行比較。結果 原髮性高血壓Ⅲ組、Ⅳ組三尖瓣血流頻譜A值增大，E/A ＜1，與對照組及高血壓Ⅰ組、Ⅱ組比較，差異有統計學意義(P＜0.05)。原髮性高血壓各組Em/Am均＜1；不同組間Em/Am比較，差異有統計學意義(P＜0.05)。結論 組織多普勒顯像比脈遲多普勒更早、更敏感地髮現原髮性高血壓導緻的右室舒張功能受損，且隨著左心室室構的不同，右室舒張功能減退的程度有所差彆。

Objective To assess right ventricular diastolic function in patients with essential hypertension using tricuspid valve flow spectrum and tricuspid annulars motion dectected by echocardiography. Methods According to Ganau′s categories, 124 patients with essential hypertension were enrolled,which were divided into four groups:normal left ventricular configurational group (group Ⅰ, n =32 ), centripetal reconstruction group (group Ⅱ, n =30), centripetal hypertrophy group ( group Ⅲ, n =32), eccentric hypertrophy group ( group Ⅳ, n =30 ). Control group consisted of 35 normal subjects pulsed wave Doppler(PW) data and tissue Doppler imaging(TDI) data were acquired from tricuspid and its' annulus respectively on apical four chamber view. Results EPA ＞ 1 was observed in control group as well as group Ⅰ and Ⅱ ,while E/A ＜ 1 in group Ⅲ and group Ⅳ ,there were significant differences between them. Em/Am ＜ 1 was observed in all of patients with hypertension,there were significant differences among them( P ＜ 0.05 ) .Conclusion Tissue Doppler imaging was more sensitive than pulse Doppler in evaluating decreased right ventricular diastolic function in patients with essential hypertension, and the decrement of the function was different in degree based on variant left ventricular configurations.
