经食道心脏超声检测右心室功能的临床研究

Clinical Study on Transesophageal Echocardiographic Evaluation ot RightVentricul ar Function

以经食道心脏超声技术对一系列１００例心脏病患者检测了右心室功能。结果显示，公式法或超声仪自动显示的右心室容积所计算的右心室射血分数均与同时检测的左心室射血分数近似（Ｐ＞０．０５）。检测的右心室的血分数或右心室长径、周径缩短分数均与患者临床心功能级别间有良好相关性（ｒ分别为一０．８０、一０．６４、一０．５２，ｎ＝１００，Ｐ＜０．０１）。结论是，经食道心脏超声为可信赖的右心室功能评价措施，安全、无创、可连续重复观测为其优点。

consecutive patients with heart dis-eases were studied on their right ventricular functionby transesophageal echocardiography. The resultsshowed that there were no significant differences incardiac ejection fraction between right ventricle andleft ventricle which was measured simultaneously asacontrol. The right ventricular ejection fraction,theright ventricular length or circumference shorteningFractions were all correlated well with the clinicalgrades of the cardiac function(r=一0.80,一 0.64,-0.52,n=100,P<0.01 ,individually).In our conclu-sion,it is believed the transesophageal echocardio-graphy was a reliable method to evaluate that rightventricular function,safe, non一 invasive and allow-ing Consecutively repeat were its advantages.
