房室平面位移评价左室舒张功能的价值

目的 探讨房室平面位移（ＡＶＰＤ）评价左室舒张功能的价值。方法 分别用脉冲多普勒超声、组织多普勒成像（ＤＴＩ）和Ｍ型超声在心尖四腔观检测１９８例患。结果 ＡＶＰＤ与经二尖瓣口血流频谱曲线比较，以比值〈１为标准，两间的发生率有显差异（Ｐ〈０．０２５），以ＡＶＰＤ预测ＥＰ／ＡＰ〈１的敏感性、特异性、准确性分别为６５．５７％、９４．４％和８０．１６％。ＡＶＰＤ、ＥＳ／Ａ与ＤＴＩ、Ｅａ／Ａａ之间无显差异（Ｐ〉０．９）。Ｅｓ／Ａｓ预测Ｅａ／Ａａ〈１的敏感性、特异性和准确性分别为９２．９１％、９０．０％和９１．６％。结论 ＡＶＰＤＥｓ／Ｅａ是评价左室舒张功能的一个有用的方法。

Evaluation of left ventricular diastolic function by echocardiographic atrioventricular plane displacement

Purpose To evaluate left ventricular diastolic function by echocardiographic atrioventriculae plane displacement(AVPD) .Methods One hundred and niney eight subjects were examined by M - mode Echocardiography, Doppler Tissue imaging and AVPD in apical 4 chamber viem respectively. Results To comparison between the values of AVPD and PDE,Significance difference(P < 0.025) were found, when ratio is less than one EA/AA of AVPD identified Ep/Ap < 1 with sencitivities of 65.57 % , specificities ol 94.4 % and accuracy of 80.16 % . No significance difference (P > 0.9) can be found between the value of Ea/Aa in DTI and Es/As in AVPD. Es/As of AVPD identified Ea/Ad < 1 of DTI with sensitivities of 92.91 % , specificities of 90.0% and accurracy of 91.67% . Conclusion Es/As of AVPD appeal's to be a useful method in evaluation of left ventricular diastolic function.
