| 摘 要： | 目的 :比较 M-型彩色多普勒测量的舒张早期左室内血流传播速度 (velocity of propagation,Vp)的两种方法 ,探讨 Vp的生理意义。方法 :2 0例受试者 (包括正常人和患者 ) ,每例受试者分别用 Garcia和 Takatsuji两种方法测量 Vp值。结果 :两种定义 Vp的方法的测值具有显著性差异 (P<0 .0 5 )。结论 :本文认为在临床上应采用Garcia的方法测量 Vp,因为该方法不依赖于单个像素点的选择 ,且在不同病例间具有一致性。

| Abstract: | Objective:To evaluate two methods including their physiologic implications for determining left ventricular propagation velocity (Vp) from color M-mode Doppler transmitral flow images.Methods:Vp of 20 subjects was measured by using Garcia's and Takatsuji's methods statistically compared.Results:There were significant differences in Vp numerical values computed between the two methods in the same subjects( P <0.05)resulted from their different definitions of methods.Conclusions:We suggest to first choose Gracia's method which is independant upon the selected unit pixal and identical in different patients. |
