    This study introduces a new fetal monitor that measures intervals in the fetal cardiac cycle, like the R-wave to second heart sound (R-S2) interval. These measurements can reveal changes in fetal cardiac performance due to drugs or acidemia.

    Area of Science:

    • Cardiology
    • Fetal Medicine
    • Medical Instrumentation

    Background:

    • Fetal cardiac monitoring is crucial for assessing well-being during pregnancy and labor.
    • Existing intrapartum monitors may not capture subtle changes in fetal cardiac performance.
    • Understanding fetal cardiac intervals can provide insights into fetal response to various physiological and pathological conditions.

    Purpose of the Study:

    • To describe a novel recorder for continuous measurement of fetal cardiac cycle intervals.
    • To evaluate the utility of specific intervals, such as R-S2, in reflecting fetal cardiac performance.
    • To demonstrate how these intervals are affected by factors like drugs and acidemia.

    Main Methods:

    • Development of a recorder capable of measuring multiple fetal cardiac intervals.

    Related Experiment Videos

  • Primary focus on measuring the R-wave to second fetal heart sound (R-S2) interval.
  • Exploration of other measurable intervals including R-R, R-A0, R-Pl, and R-Sc.

    • Main Results:

    • The recorder successfully measures various fetal cardiac intervals continuously.
    • The R-S2 interval and other measured intervals are shown to reflect fetal cardiac performance.
    • Alterations in these intervals correlate with the presence of drugs and acidemia in the fetus.

    Conclusions:

    • The described recorder offers a new tool for detailed fetal cardiac assessment.
    • Measured fetal cardiac intervals provide valuable information on fetal cardiac function.
    • This technology has potential applications in monitoring fetuses exposed to drugs or experiencing acidemia.
