近10年来,二维超声心动图和多普勒技术广泛应用于各种心功能研究,为临床上提供了一种简便,可靠的无创性方法.本文重点讨论该技术测定心输出量、右室收缩功能和左右心室舒张功能的方法.采用超声心动图技术测定左室收缩功能的方法已较成熟。近年来,许多学者又把二维超声和多普勒技术应用于心输出量、右室收缩功能和左右心室舒张功能等方面的研究,结果表明,超声心动图测定各种心功能的方法已日臻完善。
In the recent 10 years, two-dimensional echocardiography and Doppler technique are widely used in various cardiac function studies, providing a simple and reliable noninvasive method in clinic.This article focuses on the determination of cardiac output, right ventricular Systolic function and left ventricular diastolic function of the method of using echocardiography to measure left ventricular systolic function is more mature. In recent years, many scholars in turn two-dimensional ultrasound and Doppler techniques applied to cardiac output, right ventricular systolic function and left ventricular diastolic function and other aspects of the study, the results show that the echocardiographic determination of cardiac function has become increasingly perfect.
