This study introduces a novel deep learning approach for fetal electrocardiogram (FECG) recognition, overcoming limitations of independent component analysis (ICA). The method accurately identifies FECG signals in multi-channel data, advancing automated FECG monitoring.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Machine Learning

Background:

  • Independent Component Analysis (ICA) is a common method for extracting fetal ECG (FECG).
  • ICA results for FECG are often uncertain regarding amplitude, order, and polarity.
  • Accurate FECG recognition is crucial for non-invasive prenatal monitoring.

Purpose of the Study:

  • To develop a novel deep learning strategy for robust FECG recognition.
  • To address the uncertainties associated with ICA in FECG extraction.
  • To improve the accuracy and automation of FECG signal identification.

Main Methods:

  • A cross-domain consistent convolutional neural network (CDC-Net) was developed.
  • The output of ICA was used as input for the CDC-Net.
Keywords:
