核听诊器(又称γ-心功能仪),是应用放射性核素测定左心功能的一种简便、准确、无创伤的新型检查仪器,在微计算机控制下,自动完成测定、计算、显示和记录工作。我院自1986年以来应用核听诊器在冠心病的诊断方而获得了有意义的资料,现报道如下。一般资料仪器与方法核听诊器为北京核仪器厂生产的 FT一1908型,采用 TRS一80型微计算机,并应用该机左心功能测定的程序软件,配合应用湖南岳阳电子仪器厂生产的踏车式心功量机做运动试验。采用~(113m)InCl_3体内标记输铁蛋白法,取~(113m)InCl_3洗脱液5mci/1～2ml、静脉“弹丸式注射”。测定顺序均按本仪器的使用说明书进行。主要测定指标核听诊器能直接或通过换算获得二十几个心功能指标,本文评价了
Nuclear stethoscope (also known as γ-cardiac function meter) is a simple, accurate and non-invasive new testing instrument for radionuclide determination of left ventricular function. It automatically measures, calculates, displays and records under the control of a microcomputer jobs. Our hospital since 1986, the application of nuclear stethoscope in the diagnosis of coronary heart disease and access to meaningful information is reported below. General Information Instruments and Methods The nuclear stethoscope is a type of FT-1908 manufactured by Beijing Nuclear Instrument Factory. The TRS-80 microcomputer is used and the program software of the left heart function test is applied to the treadmill with the application of the treadmill manufactured by Hunan Yueyang Electronic Instrument Factory Heart-type machine to do exercise test. The ~ (113m) InCl_3 in vivo labeled transferrin method was used to take ~ (113m) InCl_3 eluate 5mci / 1 ~ 2ml intravenous “bolus injection.” Determination of the order according to the instrument manual. The main test indicators Nuclear stethoscope can be obtained directly or through conversion of dozens of cardiac function indicators, this article evaluated
