A new look at the neonatal electrocardiogram

D P Southall, D G Vulliamy, M J Davies

    British Medical Journal
    |September 11, 1976
    PubMed
    Summary

    Routine electrocardiograms (ECGs) in newborns revealed abnormalities in 57 of 818 infants, highlighting the need for clearer normal ranges and potentially linking ECG findings to sudden infant death syndrome.

    Area of Science:

    • Neonatal cardiology
    • Pediatric electrophysiology

    Background:

    • Electrocardiograms (ECGs) are crucial for assessing neonatal cardiac health.
    • Establishing precise normal ECG ranges in newborns is essential for accurate diagnosis.

    Purpose of the Study:

    • To define the range of normal ECG variations in newborns.
    • To investigate the correlation between ECG abnormalities and adverse neonatal outcomes, including sudden infant death syndrome and congenital cardiac anomalies.

    Main Methods:

    • Prospective study recording ECGs in 818 newborn infants between April 1975 and April 1976.
    • Analysis of ECG recordings falling outside the accepted normal range.
    • Histological examination of cardiac conducting systems in deceased infants.

    Main Results:

    Related Experiment Videos

    • 57 out of 818 newborns had abnormal ECG recordings.
    • Twelve infants presented with asymptomatic conduction abnormalities, three requiring treatment.
    • Two sudden infant deaths were recorded; one infant had ECG conduction abnormalities and histological evidence of conducting system defects.
    • Ten congenital cardiac anomalies were identified, four through abnormal screening ECGs.

    Conclusions:

    • Routine neonatal ECG screening can detect significant cardiac issues, including congenital anomalies.
    • Abnormal ECG findings in newborns may be associated with an increased risk of sudden infant death syndrome.
    • Further research is warranted to clarify the link between conducting tissue abnormalities and sudden infant death syndrome.
