This study introduces a novel method for analyzing fetal electrocardiogram (FECG) signals to detect fetal heart rate (HR) and average FECG complexes from maternal abdominal recordings. The technique utilizes a triple parametric transform with square wave functions for improved signal correlation.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Medical Physics

Background:

  • Fetal electrocardiogram (FECG) analysis is crucial for monitoring fetal well-being.
  • Detecting weak FECG signals from maternal abdominal recordings presents significant challenges.
  • Existing methods like Fourier transform may not optimally correlate with FECG signal characteristics.

Purpose of the Study:

  • To propose a new theoretical basis for FECG signal analysis.
  • To develop a method for detecting fetal heart rate (HR) from weak FECG signals.
  • To enable the computation of an average FECG complex from abdominal recordings.

Main Methods:

  • A novel triple parametric transform is introduced.
  • Analyzing functions based on square wave trains are utilized.

  • These functions offer higher correlation with ECG signals compared to standard Fourier transform functions.

    • Main Results:

    • The proposed method provides a theoretical framework for FECG analysis.
    • It is designed to accurately detect fetal HR even from weak signals.
    • The method facilitates the generation of an average FECG complex.

    Conclusions:

    • The developed triple parametric transform offers a promising approach for FECG analysis.
    • This method can enhance the detection of fetal HR and FECG complexes.
    • The technique has broader applicability to other weak, quasi-periodic sharp signals.
