Cardiac pre-ejection period during prenatal life

J L Evers

    Gynecologic and Obstetric Investigation
    |January 1, 1980
    PubMed
    Summary

    Determining the pre-ejection period (PEP) of the fetal heart offers insights into fetal well-being. This metric may serve as an early indicator of fetal distress during labor.

    Area of Science:

    • Perinatal medicine
    • Cardiovascular physiology
    • Fetal monitoring

    Background:

    • Fetal heart rate monitoring is the primary method for assessing unborn child's condition.
    • Current methods lack sufficient information on fetal cardiac performance and distress.
    • The pre-ejection period (PEP) offers a potential new metric for fetal cardiac assessment.

    Purpose of the Study:

    • To review the potential of fetal pre-ejection period (PEP) monitoring for assessing fetal cardiac performance.
    • To evaluate PEP as an indicator of cardiovascular adjustments during fetal distress.
    • To explore the clinical utility of human fetal PEP monitoring.

    Main Methods:

    • Review of data from chronically instrumented fetal animals.
    • Analysis of preliminary data from human perinatal research.
    • Anticipation of future developments in human fetal PEP recording.

    Main Results:

    • Fetal heart rate monitoring alone provides limited information.
    • PEP measurement may offer insights into fetal heart performance in utero.
    • Preliminary data suggest PEP's potential in assessing fetal cardiovascular status.

    Conclusions:

    • The pre-ejection period (PEP) shows promise for fetal cardiac assessment.
    • PEP may serve as an early antepartum indicator of fetal distress during labor.
    • Further research and clinical development of fetal PEP monitoring are warranted.
