近年来的研究表明,阻抗法测定心输出量的准确性与染料稀释法相近似,而且安全简便,重复性好,已在临床推广使用。导纳法与阻抗法一样,都是无创性检查心功能的一种新方法,两种方法测定心输出量有较好的相关性,且前者在设计上简化计算,使其精确度有所提高。本文报告我们用导纳图仪测定健康成年人、心脏病患者及心衰患者的各项心功能指标,并对其结果进行分析。对象和方法:健康成年人80名,年龄16岁至65
In recent years, studies have shown that the accuracy of impedance determination of cardiac output and dye dilution method similar to, and safe and easy, reproducible, and has been in clinical use. As with the impedance method, the admittance method is a new method of noninvasive examination of cardiac function. The two methods have a good correlation between cardiac output and the former is designed to simplify the calculation and improve its accuracy . In this paper, we report the cardiac function of healthy adults, patients with heart disease and patients with heart failure by admittance plotter, and analyze the results. Subjects and Methods: 80 healthy adults, aged 16 to 65
