Neonatal electrocardiographic changes in relation to cardiotocographic changes.

K H Hökegård, K Karlsson, H Lilja

    British Journal of Obstetrics and Gynaecology
    |March 1, 1978
    PubMed
    Summary

    Immediate postpartum electrocardiograms (ECG) reveal significant T-wave changes in newborns exposed to abnormal labor patterns. These ECG alterations correlate with lower Apgar scores and increased neonatal complications, indicating hypoxic stress.

    Area of Science:

    • Neonatal Medicine
    • Cardiology
    • Obstetrics

    Background:

    • Cardiotocography (CTG) monitors fetal well-being during labor.
    • Abnormal fetal heart rate patterns during labor may indicate hypoxic stress.
    • Postnatal assessment of neonatal adaptation is crucial.

    Purpose of the Study:

    • To investigate the utility of immediate postpartum electrocardiograms (ECG) in identifying hypoxic stress in newborns.
    • To correlate ECG findings with labor cardiotocographic patterns and neonatal outcomes.

    Main Methods:

    • Electrocardiograms (ECG) were performed immediately after birth on 57 infants.
    • Infants were divided into two groups based on labor cardiotocographic patterns (normal vs. abnormal).
    • ECG changes, particularly in the S-T segment and T-wave, were quantified using a scoring system.

    Main Results:

    • High and peaked T-waves (elevated T/QRS-ratios) were significantly more prevalent in infants with abnormal labor CTG patterns.
    • Infants exhibiting ECG changes had significantly lower Apgar scores.
    • Neonatal complications were more frequent in infants with abnormal labor CTG patterns and associated ECG changes.

    Conclusions:

    • Immediate postpartum ECG is a valuable tool for assessing accumulated hypoxic stress during labor.
    • ECG findings can provide objective evidence of fetal distress not fully captured by cardiotocography alone.
    • Early identification of hypoxic stress through ECG may guide neonatal management and improve outcomes.
