Abstract
Objective
To generate data of electrocardiogram (ECG) parameters according to gestational age in Indian newborns.
Methods
An observational study was carried out over 7 months in neonatology unit of a tertiary care teaching hospital. Following auscultation, ECG parameters were recorded simultaneously in 12 leads, on third day of life, in hemodynamically stable neonates. Data from 364 babies were analyzed, keeping at least 30 records for each gestational age between 30 to 42 weeks.
Results
There was no difference in mean heart rate recorded through auscultation and ECG traces. The mean (SD) values recorded were: P wave duration 0.04 (0.01) s, P wave amplitude 1.3 (0.4) mm, T wave duration 0.07 (0.02) s, T wave amplitude 1.1 (0.6) mm, PR interval 0.09 (0.02) s, QRS duration 0.04 (0.01) s, QT interval 0.26 (0.02) s, QTc 0.4 (0.03) s and QRS axis 127 (22) degree. Gestation age-wise percentile charts of different ECG parameters were generated.
Conclusion
These gestational age-wise percentile charts of different ECG parameters for Indian newborns can be used as reference for neonatal ECG.
