Can one monitor track two Babies' heartbeats at once?
NCT ID NCT06835647
First seen Sep 22, 2026 · Last updated Sep 23, 2026 · Updated 1 time
Summary
Researchers are testing a new maternal fetal monitoring device designed to continuously track the heart rates of both babies in a twin pregnancy. The study enrolls 18 pregnant women carrying twins at 30 weeks or later. Participants wear the investigational monitor while a standard ultrasound imaging device records at the same time, so researchers can compare how well the new device captures two distinct fetal heart rates and the mother's pulse.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an investigational maternal fetal monitoring device that uses ultrasound to track fetal heart rates
- What this could lead to
- If it works, the device could give doctors a clearer, continuous picture of both babies' heart rates during twin pregnancies, which may help guide care decisions.
- What could go wrong
- This is a small device performance study, not a test of whether better monitoring improves outcomes. The device may fail to reliably separate the two babies' heart signals, and the results may not apply to all twin pregnancies.

Inclusion Criteria: 1. Able and willing to provide written informed consent. 2. Twin pregnancy. 3. Aged 18+. 4. Greater than or equal to 30 0/7 weeks gestation. 5. Patient has none of the exclusion criteria. Exclusion Criteria: 1. Non-twin pregnancy. 2. Involvement in another clinical trial currently or previously in this pregnancy that, in the investigator's opinion, would affect the conduct of this study. 3.
