了解老年人心功能及其异常的特殊性,对老年循环系统疾病的诊断、治疗具有重要意义。本文首先介绍作者进行心放射图和心回声图检查所得循环系统各项指标的测值,并结合最近文献资料对老年人心功能判定时应注意的问题作简要叙述。心放射图检查作者开展了心放射图(RCG)模拟分析法作为一种无创性循环功能检查,对由此法所得各种循环功能指标确定其正常范围和各年龄组的差异。这种方法是将碘标记的人血清白蛋白(RISA)作快速静脉注射,由对向心脏的闪烁探头记录出放射性稀释曲线。用模拟计算机将此曲线模拟成由右心、
To understand the special features of heart function and abnormalities in the elderly is of great significance for the diagnosis and treatment of diseases of the elderly circulatory system. In this paper, we first introduce the measurement of various indexes of the circulatory system obtained from the cardiac radiogram and the echocardiogram of the author, and briefly describe the problems that should be paid attention to when judging the cardiac function of the elderly with the latest literature. Cardiac Radiographic Examination The authors conducted cardiac radiography (RCG) simulation analysis as a noninvasive circulation function test to determine the differences in normal range and age groups for various circulatory function indices obtained by this method. This method is a rapid intravenous injection of iodine-labeled human serum albumin (RISA), the radioactive dilution curve recorded by the scintigraphy to the heart. Using a simulation computer to simulate this curve from the right heart,
