ABSTRACT
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.
