本文采用职业、性别、年龄配对(≤3岁)分析的方法,对563例献血员与356例非献血员的P-R间期、P-R指数进行比较。经配对t检验,未发现献血引起P-R间期与P-R指数延长。同时,对不同总献血量组的P-R间期与P-R指数进行比较,经方差分析,各组上述参数的差异无显著性(P>0.05)。
In this study, P-R interval and P-R index were compared between 563 blood donors and 356 non-blood donors by means of occupation, sex and age matched (≤3 years old). By paired t test, no blood donation caused P-R interval and P-R index prolongation. At the same time, P-R interval and P-R index of different total blood donation volume groups were compared. There was no significant difference between the above parameters (P> 0.05) by variance analysis.
