近年来,应用胸阻抗图(ICG)测定心血管功能,因其方法简便,无创伤性,与其它无创性心功能检测指标的相关性好,在国内已受到普遍重视。但是在胸阻抗法计算心输出量的公式中包括基础阻抗值(Z_0)。因为测量 Z_0 的误差较大,使心输出量的计算受到影响。为准确计,于1976年以来国际上已有胸导纳图方
In recent years, the application of thoracic impedance spectroscopy (ICG) in the determination of cardiovascular function, because of its simple, non-invasive method, and other noninvasive cardiac function test has good correlation in the country has been generally valued. However, in the chest impedance method to calculate the cardiac output in the formula includes the basic impedance value (Z_0). Because of the large error of measuring Z_0, the calculation of cardiac output is affected. To be accurate, there has been an international conspiracy of induction since 1976
