左心室射血分数(EF)创伤性方法测量结果虽然较准确,但目前尚不能广泛使用。近年来人们特别注意简单的无创性EF测量方法的探讨。我们曾用超声心动图(UCG)法、心缩间期法(STD、心尖搏动图(ACG)法测定正常人EF值。本文用无创性方法测定风心病二尖瓣狭窄和冠心病人的EF,与正常人比较有明显差别,肯定了这些方法的临床实用价值。
Although the measurement of left ventricular ejection fraction (EF) traumatic method is more accurate, it is not yet widely used. In recent years, people pay special attention to the discussion of simple noninvasive EF measurement methods. We have used echocardiography (UCG) method, systolic interval method (STD, apex beat map (ACG) method to determine the normal EF value of non-invasive method for the determination of rheumatic mitral stenosis and coronary heart disease in patients with EF , Compared with normal people have obvious differences, affirmed the clinical practical value of these methods.
