目的：探讨不同胎龄新生儿心电图中P-R间期、QRS时限及QTLc特点。方法：将152例不同胎龄新生儿根据胎龄不同分为4组：28～30周为A组，31～33周为B组，34～36周为C组，37～40周为D组；对所有新生儿分别测量心电图P-R间期、QRS时限、QTLc、QRS振幅、RV1振幅、TV1和TV5振幅。结果：P-R间期随胎龄的增加而延长，组间比较差异有统计学意义（F＝11.362，P＝0.0009）。但QRS时限和QTLc无明显延长，组间比较差异无统计学意义（P＞0.05）；QRS和RV1振幅均随胎龄的增加而升高，两两比较差异有统计学意义（F＝6.763、F＝18.096，P＝0.0087、P＝0.0014）；TV1和TV5振幅均随胎龄的增加而升高，两两比较差异有统计学意义（F＝34.981、F＝20.783，P＝0.0012、P＝0.0065）。结论：不同胎龄新生儿心电图P-R间期与胎龄相关，QRS时限及QTLc与胎龄无明显相关。
目的：探討不同胎齡新生兒心電圖中P-R間期、QRS時限及QTLc特點。方法：將152例不同胎齡新生兒根據胎齡不同分為4組：28～30週為A組，31～33週為B組，34～36週為C組，37～40週為D組；對所有新生兒分彆測量心電圖P-R間期、QRS時限、QTLc、QRS振幅、RV1振幅、TV1和TV5振幅。結果：P-R間期隨胎齡的增加而延長，組間比較差異有統計學意義（F＝11.362，P＝0.0009）。但QRS時限和QTLc無明顯延長，組間比較差異無統計學意義（P＞0.05）；QRS和RV1振幅均隨胎齡的增加而升高，兩兩比較差異有統計學意義（F＝6.763、F＝18.096，P＝0.0087、P＝0.0014）；TV1和TV5振幅均隨胎齡的增加而升高，兩兩比較差異有統計學意義（F＝34.981、F＝20.783，P＝0.0012、P＝0.0065）。結論：不同胎齡新生兒心電圖P-R間期與胎齡相關，QRS時限及QTLc與胎齡無明顯相關。

Objective:To study the features of ECG P-R interval, QRS time and QTLc in newborns with different gestational age.Methods:152 newborns with different gestational ages in neonatal of our hospital from 2014 to 2015 were subjects of our study.They were divided into four groups, Group A consists of newborns of age 28-30 weeks,group B 31 -33 weeks, group C 34 -36 weeks, group D 37 -40 weeks.All newborns had their P-R intervals,QRS time, QTLc, QRS amplitudes, RV1 amplitudes, TV1 and TV5 amplitudes measured.Results: P-R interval prolongs with increasing gestational age, and the difference was significant between two groups ( F =11.362,P=0.000 9).QRS duration and QTLc were not significantly longer, and the difference between the two groups was insignificant ( P>0.05 );QRS and RV1 amplitude rises with increasing gestational age, and pairwise comparisons were with significantly difference(F=6.763,F=18.096;P=0.008 7,P=0.001 4);Both TV1 and TV5 amplitudes increase with increasing gestational age; pairwise comparisons yields significant difference ( F =34.981, F=20.783;P=0.001 2,P=0.006 5).Conclusion: P-R interval is correlated with gestational age of neonates, QRS time and QTLc are not significantly related to gestational age.
