左室舒张功能对肺静脉血流的影响

用脉冲多普勒技术检测３０例正常人，５０例左房代偿功能正常的高血压心脏病和冠心病、以及２０例左房功能失代偿的高血压心脏病或冠心病患者的肺静脉血流。结果表明：肺静脉血流频谱中的Ｓ峰速、Ｄ峰速及Ｄ／Ｓ值，是评价左室舒张功能的一批新指标，综合运动用上述指标，可对左室舒功能作出正确评价。

FInfluence of Left Ventricular Diastolic Function on Blood flow Frequency Diagram of Pulmonary Veins

Pulse wave Doppler technique was used to detect the blood flow of pulmonary veins of30 normal cases, 50 patients with hypertension, heart disease, coronary heart disease,whose compensatory function of left atria are normal, and 20 patients suffering from bypertension, heart disease orcoronary heart disease, whose function of left atria are deconpensated. The results showed that the systolic(s) and diastolic(D)heak velocities, atrial systolic(A),peaks and D/S ratio of the blood flow frequency diagram of pulmonary veins are new indexes to evaluate diastolic function of left ventricle. using the above barameters comprehensively, correct estimation of left ventricnlar diastolic function can beachieved.
