Abstract Introduction: Since electrocardiography along with the other diagnostic procedures, is applied in seeking cardiac disease, so perceiving normal and abnormal electrocardiography patterns in newborns, accelerates the diagnosis of these diseases. On the other side some ECG parameters of term and premature newborns, which changes through life span, are different from each other. Objective: There was no study done in our center to compare the electrocardiogram of term and premature neonates so we decided to compare their EKGs and its differences with other centers in the world. Materials and Methods: During 2002, from 30 term newborns (gestational age of > 38 weeks) and 30 premature (GS< 38 weeks) who were born in hospitals of Shiraz University of medical sciences and age 24-96 ours were chosen. And a complete EKG (12 leads) was conducted on lying position when newborn was calm and alert. All neonates were assessed fully for underlying diseases that could affect their EKG. All EKGS were assessed and compared as regard to heart rate, axis of heart, voltage, P wave duration and R wave in QRS complex. Comparative statistics was done using SPSS soft ware with fisher exact method. Results: QRS axis in full term neonate is shifted to the right and to the left in premature neonates (P<0.05). Duration of P and QRS waves in term is longer than those in premature babies (P<0.05). Voltage of P wave in premature neonates is higher than that in the term babies. We didn't find significant difference between R wave voltages in these two groups. Conclusion: The electrocardiogram of premature infants is different from the term ones in axis, P voltage and QRS duration.
