在估价心室功能时,多普勒超声术与其他超声技术相比,处于次要地位.多普勒超声术不能直接估计心室的几何形态和动力改变,但多普勒法能不依靠心室几何形态而对心室功能进行估价并能取得解剖学所不能提供的资料.多普勒可和M型、两维超声检查同时进行,只需多费大约15分钟,而且安全,无不适,价格也较M型超声图低.在目前,多普勒超声术可视为估价心室作功的一种辅助手段.心室功能的评价
Doppler ultrasound plays a secondary role in the assessment of ventricular function compared with other ultrasound techniques, which can not directly estimate ventricular geometry and motility changes, but Doppler does not rely on ventricular geometry Valuation of ventricular function and access to anatomical data can not be provided.Doppler and M-mode, two-dimensional ultrasound at the same time, just spent about 15 minutes, but also safe, no discomfort, the price is more than M Type ultrasound map is low. At present, Doppler ultrasound can be used as a valuation method of ventricular assist power means. Evaluation of ventricular function
