Fetal electrocardiograms, direct and abdominal with reference heartbeat annotations.

Area of Science:

• Biomedical Engineering
• Signal Processing
• Obstetrics

Background:

• Fetal heart rate (FHR) variability is crucial for assessing fetal well-being.
• Direct fetal electrocardiogram (FECG) provides reliable signals but is invasive and limited to labor.
• Abdominal FECG offers a non-invasive alternative but suffers from lower quality and interference.

Purpose of the Study:

• To present a novel dataset of abdominal and direct FECG signals.
• To facilitate the development of improved methods for FECG signal analysis.
• To advance the accuracy and application of abdominal electrocardiography in fetal monitoring.

Main Methods:

• Collected 10 twenty-minute pregnancy and 12 five-minute labor FECG signals.
• Simultaneously recorded abdominal and direct FECG during labor.
• Utilized automated detection with expert correction for reference pregnancy signals.

Main Results:

• The dataset includes signals with diverse interferences and clinically relevant FHR patterns.
• Provides simultaneous abdominal and direct FECG recordings for comparative analysis.
• Offers validated pregnancy FECG signals for research purposes.

Conclusions:

• The released dataset enables the scientific community to develop new FECG analysis techniques.
• This resource is expected to enhance the accuracy of non-invasive fetal monitoring.
• Advances in abdominal electrocardiography can lead to improved fetal state assessment.
