Area of Science:

  • Biomedical Engineering
  • Medical Informatics
  • Traditional Chinese Medicine

Background:

  • Computerization of traditional Chinese pulse diagnosis (TCPD) is an emerging field.
  • Previous research focused on pulse shape and position, neglecting pulse rhythm analysis.
  • Identifying pulse rhythms is crucial for accurate diagnosis.

Purpose of the Study:

  • To develop a method for distinguishing rhythmic and arrhythmic pulse patterns.
  • To apply Lempel-Ziv decomposition for classifying arrhythmic pulses.
  • To evaluate the accuracy of the proposed rhythm classification method.

Main Methods:

  • Development of a novel algorithm to differentiate pulse rhythms.
  • Application of Lempel-Ziv decomposition for detailed arrhythmic pulse classification.

Related Experiment Videos

  • Experimental validation using 140 clinical pulse recordings.

    • Main Results:

    • The proposed method successfully distinguished between rhythmic and arrhythmic pulse patterns.
    • Lempel-Ziv decomposition effectively classified various arrhythmic pulse types.
    • Achieved a high classification accuracy of 90.7% for pulse rhythms.

    Conclusions:

    • The developed method offers a new approach to computer-aided pulse diagnosis.
    • Rhythm analysis is a viable and accurate component of automated TCPD.
    • This research opens avenues for further investigation into pulse rhythm-based diagnostics.
