Probably not a fit

Patients who are in active labor will not benefit from this study as they are excluded from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This feasibility study aims to determine if a Holter ECG device can effectively capture fetal cardiac activity. Pregnant women between 32 weeks gestation and full term will have both a Holter ECG device and a standard Doppler Fetal Heart Rate (FHR) device attached to their abdomen for a 30-minute recording. The study will compare the data obtained from the Holter device with the standard Doppler FHR readings to validate the algorithm for extracting fetal heart rate from the ECG signals. The procedure will be conducted after routine antepartum testing, ensuring the safety and comfort of the participants.

Why it matters

Potential benefit: If successful, this approach could provide a more accurate and non-invasive method for monitoring fetal heart activity.

How similar studies have gone: While this approach is innovative, it is not widely tested, making it a novel exploration in fetal monitoring.
