摘　　要：应用脉冲多普勒技术对照研究了５８例正常人和５６例收缩功能正常的高血压病患者二尖瓣和肺静脉的血流频谱参数。结果显示：高血压病组二尖瓣舒张期血流参数Ｅｐ、Ｅｉ、Ｅ／Ａ较正常组显著降低，ＡＦＦ显著升高；其肺静脉血流参数Ｓｐ、Ｓｉ、ＳＦ显著升高而Ｄｐ、Ｄｉ显著降低，即心室收缩期肺静脉向左房的回流速度及回流分数增加，舒张期的回流则减慢。说明高血压病患者在心功能代偿期，不仅存在左室舒张充盈的异常，同时也存在肺静脉的回流异常。This study investigated the mitral valve and pulmonary venous flow parameters in 58 normal subjeets (NS) and in 56 patients with primary hypertension (HT,with normal left ventrioular systolic function)using pulsed Doppler echocardiography.The results showed that the diastolic parameters of mitral flow Ep,Ei.E/A ratio were decreased and AFF was increased significantly,and the pulmonary venous flow parameters Sp,Si,SF were increased,while Dp,Di decreased significantly,both compared with NS.It was concluded that in patients with HT exist not only abnormal left ventricular diastolic filling,but also abnormal pumonary venous flow drainage,despite their normal left ventricular systolic function.
