| 摘 要： | 应用经食管脉冲多普勒超声在术中测定了７６例不同心脏病患者的左上肺静脉血流频谱。结果显示：Ｒｖ和ＳＦ％分别与同步测定的平均左房压间存在高度相关性（ｒ＝－０．８８和ｒ＝－０．８７）；以ＳＦ％小于５２％预测平均左房压大于２．０ＫＰａ时，其敏感性和特异性分别为９３％和８５％。结论认为，应用经食管脉冲多普勒测定肺静脉血流频谱能准确估测平均左房压，为定量评价左室舒张功能提供了新途径

| Abstract: | Flow velocities and integrals of left upper pulmonary vein were measured by transesophagenl pulsed wave Doppler echo(TEE pw)during the cardiac surgery in 76 patients with various heart diseases.The results revealed that there were high correlations respectively between Rv and mean left atrial pressure(LAP)(r=-0 88,P<0 001)and between SF% and mean LAP(r=-0 87,P<0 001),and SF% less than 52% predicting mean LAP greater than 2 0 KPa with sensitivity and specificity of 93% and 85%,respectively.It is concluded that pulmonary venous flow velocities and integrals by TEE pw can quantify accurately mean LAP and further more provide a new approach for the quantitative assessment of left ventricular diastolic function. |
