ECG changes in asphyxia neonatorum.

Abstract

Twenty five asphyxiated neonates had ECG changes consistent with degree of asphyxia. Equivocal changes were found in mild asphyxia and changes suggestive of myocardial infarction were seen with severe asphyxia. In most cases, the changes reverted to normal within two weeks signifying great ability of the neonatal heart to withstand hypoxic insult. Four babies with severe asphyxia having ECG changes suggestive of acute myocardial infarction expired within 48 hours of birth.
