目的 观察不同胎龄新生儿心电图T波的特点.方法 不同胎龄新生儿共142例,按胎龄分为4组:28～30周组、31～33周组、34～36周组、37～40周组,观测心电图各导联T波情况.结果 28～30周组、31～33周组、34～36周组、37～40周组Tv1振幅[mV,中位数(四分位数间距)]分另4为-0.10(-0.30～0.10)、-0.10(-0.30～0.15)、-0.10(-0.45～0.25)、0.10(-0.30～0.70),TV1振幅随胎龄增长而增高,各组间差异有显著性(Z=22.535,P=0.000);TV5振幅[mV,中位数(四分位数间距)]分别为0.10(-0.10～0.30)、0.10(-0.20～0.30)、0.15(-0.05～0.25)、0.10(-0.10～0.50),各组间无明显变化,差异无显著性(Z=0.202,P=0.977).I、aVL导联T波低平、倒置及各导联T波均低平现象的发生率随胎龄增长而减少,差异有显著性(P<0.05).结论 不同胎龄新生儿TV1振幅、T波异常率与胎龄增长有相关性,TV5振幅与胎龄增长无相关性.

Objective To evaluated T-wave characteristics in newborn infants with different gestational age. Methods One hundred and forty-two newborn infants were divided into four groups based on the gestation age consisting of the 28～30 weeks group,31～33 weeks group,34～36 weeks group and 37～40weeks group, respectively. The T-wave characteristics of electrocardiogram were compared among the newborn infants of four groups. Results TV1 amplitudes ( mV, median ( interquartile range) ) of 4 groups were -0. 10( -0. 30～0. 10), -0. 10( -0. 30～0. 15), -0. 10( -0. 45～0. 25 ) and 0. 10( -0. 30～0. 70) ,respectively. There was a statistical elevation of TV1 amplitude with the increase of the gestational age. TV5 amplitudes( mV, median ( interquartile range ) ) of 4 groups were 0. 10 ( - 0. 10～0. 30), 0. 10 ( - 0. 20～0. 30) ,0. 15( -0. 05～0. 25) and 0. 10( -0. 10～0. 50) ,respectively. No significant differences of TV5 amplitudes were found among 4 groups. The incidences of low or inverted T-waves in leads I and aVL, or low and flat T-waves in all leads reduced significantly with the increase of the gestational age. Conclusion The TV1 amplitude and the incidence of abnormal T-wave in newborn infants are correlated to the gestational age,and TV5 amplitude is not correlated to the gestational age.
