摘要
本文采用心阻抗法测定了４０名青年学生的心灵功能．分别用Ｋｕｂｉｃｅｋ公式和况氏非线性公式计算出每搏输出量、每分输出量和心指数，并进行了性别比较。结果显示，Ｋｕｂｉｃｅｋ公式计算ＳＶ无性别差异，而况氏非线性公式计ＳＶ性别差异显著，两对方法比较，男性ＳＶ显示Ｋｕｂｉｃｅｋ法低于况氏法，而女性ＳＶ显示Ｋｕｂｉｃｅｋ法高于况氏法。这可能由于男女生的身高、颈围、胸围差异对计算的影响所致。
This paper reports the cardiac pumping function in 40 college students by impedance cardiography.The stroke volume(SV),cardiac output(CO),and cardiac index(CI) were separately calculated by Kubicek formula and Kuang's non-linear formula and were compared between males and females.The results show that the SV by Kubicek formula has no difference,while a significant differ ence is found in the SV by Kuang's non-linear formula.In comparison of the two methods,the SV by Kubicek formlula is lower than that by Kuang's non-linear formula in boy students,and the SV by Kubicek formula is higher than that by Kuang's non-linear formula in girl students.This may be explained by the difference in height,neck measurement,and bust of male and female students.
