Objective:

To develop a consensus-based ambulatory fetal heart rate monitoring (FHRM) guide for pregnancies complicated by or at risk of fetal arrhythmias.

Approach:
    Key Findings:
    • 90-95% of fetuses with high-risk arrhythmias can be live-born with early detection and management.
    • Ambulatory FHRM can detect new-onset or recurrent fetal arrhythmias effectively.
    • Current monitoring practices may not be sufficient for early detection of arrhythmias.
    Interpretation:

    Ambulatory FHRM is a promising approach for monitoring high-risk pregnancies, but implementation faces significant barriers.

    Limitations:
    • Lack of documented agreement on indications for ambulatory FHRM.
    • Inconsistent monitoring processes across institutions.
    • Limited FDA approval for devices used by non-medical individuals.
    Conclusion:

    The consensus-based guide aims to standardize ambulatory FHRM practices to improve outcomes in high-risk pregnancies.
