Electrocardiographic Parameters in Indian Newborns

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