我科对100名健康人心阻抗微分图进行了分析,认为它能客观地反映人体血流动力学变化,有临床使用价值。现摘要报道如下。对象与方法:本院健康医护人员100名,其中男女各50名。应用成都亚光电工厂生产的 SCZW-1型血流阻抗微分仪(叠加R波),连接于KDY-1型心电心音图机,纸速50毫米/秒。各项观察指标的计算公式从略。结果及讨论: 1.心输出量的估计对左室功能的判断有很大的价值,根据Kubicek公式,计算每搏输出量。本组心脏指数4.14±1.44,与创伤性方法比较,略高于Fick氏法的3.63±0.73,与赵广胜染料稀释法的4.23±1.32相近。
Our department analyzed the differential impedance diagram of heart impedance in 100 healthy people and thought it could objectively reflect the changes of human hemodynamics and has clinical value. The summary is reported below. Subjects and Methods: There are 100 health and medical personnel in our hospital, 50 of them men and women. SCZW-1 blood flow impedance differential meter (superposed R wave) produced by Chengdu Optoelectronics Factory was connected to a KDY-1 type electrocardiograph machine at a paper speed of 50 mm / sec. The calculation of the various indicators of measurement omitted. Results and Discussion: 1. The estimation of cardiac output is of great value in judging left ventricular function. The stroke volume is calculated according to Kubicek’s formula. The cardiac index of this group was 4.14 ± 1.44, which was slightly higher than that of Fick’s method (3.63 ± 0.73) and that of Zhao Guangsheng’s dye dilution method (4.23 ± 1.32).
