常规测定二尖瓣血流频谱。
结论P VF频谱与二尖瓣血流频谱对评价RH左室舒张功能有参照意义。
Conclusion PVF spectrum and mitral valve flow spectrum can be used to evaluate left ventricular diastolic function of RH children.
结论左房灌注分数(LAF)可以比二尖瓣血流频谱更早的体现左室舒张功能的异常改变。
Conclusions LAF can indicate the echocardiographic changes of the left ventricular abnormal diastolic function in the earlier stage than mitral valve flow indices does.

Methods 2-de, M-mode and pulsed Doppler were used to measure left ventricular geometric models, left atrial function and mitral valve flow indices.
二尖瓣口血流频谱测值一般反映了左室舒张功能状态，但对几例出现的“伪正常”频谱表现难以明确评价。
Mitral valve flow spectrum commonly reflect the state of left ventricular diastolic function, but several cases with pseudonormalization spectrum can't be clearly assessed.
