本文应用心阻抗微分波法测量69例健康人及36例冠心病人的收缩时间间期,同时用经典法测量并与之进行比较。结果表明二种方法所得的各指标数值无明显差异(P>0.05),它们之间均有密切相关。(r>0.79)。说明心阻抗微分波法测量收缩时间间期是一种合理、简单的方法。
In this paper, the heart impedance microdifacient method was used to measure the time interval of contraction in 69 healthy people and 36 patients with coronary heart disease, and compared with the classical method. The results show that there is no significant difference between the two methods (P> 0.05), which are closely related. (r> 0.79). It is a reasonable and easy way to describe the impedance time-differential impedance method.
