A Home Telemonitoring System for Wearable Fetal-ECG and EHG Acquisition During Pregnancy

Fudan University4 enrolled

Overview

The goal of this observational is to compare in describing fetal health conditions. The main questions it aims to answer are: * fetal electrocardiogram (fetal heart rate and fetal rhythm) * electrohysterography (uterine contractions). Participants will wear wearable devices and CTG equipment for monitoring for 30 minutes.If there is a comparison group: Researchers will compare clinical CTG equipment to see if this wearable device.

The investigators put the patch of the wearable device on the abdomen of the pregnant woman and continued the test for thirty minutes.

Outcomes

Primary Outcomes

The performance of this system in extracting fetal electrocardiogram (FECG)

extract fetal QRS intervals and numbers from FECG

Time frame: 2022.01-2023.08

The performance of this system in extracting electrohysterography (EHG)

use the contractions consistency index (CCI) parameters to analyze the relation between our measured EHG signal and the UC signal recorded by clinical CTG equipment.
