风湿性心脏病患者右心室舒张功能的变化

目的：观察风湿性心脏病右心室舒张功能的变化规律，为防治右心室功能不全提供进一步理论依据。方法：随机选择35例风湿心脏病患者作为研究对象，采用彩色多普勒超声心动图测量患者跨三尖瓣血流参数。结果：35例患者均存在不同程度的E峰流速下降，A峰流速增加，E／A下降，E峰减速时间缩短，结论：风湿性心脏病患者均存在不同程度的右心室舒张功能不全。

ALTERATIONS OF RIGHT VENTRICULAR DIASTOLIC FUNCTION IN RHEUMATIC HEART DISEASE

Objective Evaluate the changes of rignt ventricular diastolic function in rheumatic heart disease(RHD) to profer theoretical basis on preventing and treating for right ventricular dysfunction. Methods 35 patients were picked to collect materials of tricuspid inflow paranreters by Doppler electrocardiograms. Results All patients had degree of reduced peak early inflow velocity(E),increased peak late velocity (A):reduced E/A and increased deceleration time of E paek(Dte). Conclusion All patients were suffered from right ventricular diastolic dysfunction in RHD.
