At the Hospital de Ginecobstetricia del Centro Médico "La Raza", were taken EKG to 30 healthy premature newborn during a six month period. The first EKG was recorded 3 hours after birth, the second in 8 hours, the third in 24 h, the fourth in 48 h, the fifth in 72 hours, the sixth at the end of the first week, the seventh at the fifteen days and the eighth at 30 days after birth. The mean heart rate was 135 +/- 10 beats/min in the first week. There were heart rate elevation for the first three days after birth. The QRS mean axis were + 130 +/- 25 degrees, without changes during the study time. The QTc interval in all cases was higher than 0.42 sec. The voltage of waves R and S at right and left precordial leads were similar. At this gestational age the ventricular masses are equals. The T waves changes reflected hemodynamic changes. It is concluded what the healthy premature newborn had a typical EKG as a reflex to the cardiocirculatory adaptations.
在“拉扎”医疗中心的妇产科医院，在六个月的时间里对30名健康的早产新生儿进行了心电图检查。第一次心电图在出生后3小时记录，第二次在8小时，第三次在24小时，第四次在48小时，第五次在72小时，第六次在第一周结束时，第七次在出生后15天，第八次在出生后30天。第一周的平均心率为135±10次/分钟。出生后的前三天心率升高。QRS平均电轴为+130±25度，在研究期间没有变化。所有病例的QTc间期均高于0.42秒。左右胸前导联的R波和S波电压相似。在这个胎龄时心室质量相等。T波变化反映了血流动力学变化。得出的结论是，健康的早产新生儿有典型的心电图作为对心脏循环适应的一种反应。
