γ—心功能仪测定左心功能是应用放射性核素的示踪原理,在微计算机控制下,探测放射性药物通过心脏各房室的时间—放射性活度变化的曲线,同时获得心功能参数,是检查心血管疾病简便、准确、无创伤性的重要手段。本文报道了250例左心功能测定结果,并对获得的心功能参数作分析讨论。 γ-cardiac function of the left heart function is the application of radionuclide tracer principle, under the control of a microcomputer to detect radiopharmaceuticals through the heart of each atrioventricular time-activity curve of radioactivity, while obtaining cardiac function parameters Check the cardiovascular disease is simple, accurate, non-invasive means important. This article reports the results of 250 cases of left ventricular function test, and to obtain the parameters of cardiac function for analysis and discussion.
