采用脉冲波多普勒超声心动图测定了９９例心血管病表现心虚证患者的左心室（左室）舒张功能，并以健康人组作对比观察。结果心虚证组有不同程度的左室舒张功能障碍，随着舒张早期血流峰值速度（Ｅ）、Ｅ波流速积分（Ｅｉ）、舒张早期减速度（ＤＣ）的减低及舒张晚期血流峰值速度（Ａ）、Ａ波流速积分（Ａｉ）、Ａ／Ｅ比值、Ａｉ／Ｅｉ比值及等容舒张期（ＩＲＴ）的增高，心虚证的程度加重，其规律为气阴两虚＞心阳虚＞心气虚＞心阴虚。提示左室舒张功能多项指标是临床评定心虚证的重要依据。

英文摘要:

In this paper,left ventricular diastolic function(LVDF)of 99 Heart-Deficiency Syndrome(HDS)patients was observed with pulse Doppler echocardiogram and was compared with normal group.The results showed that different LVDF abnormalities occurred in the HDS patients.When E, Ei DC were decreased and A,Ai,A/E,Ai/Ei,IRT increased,the degree of HDS deteriorated,the pattern was Heart Qi-Yin Deficiency>Heart Yang Deficiency>Heart Qi Deficiency>Heart Yin Deficiency.In conclusion,the above parameters of LVDF could be important indices for evaluation of HDS.
