Area of Science:

  • Cardiology
  • Biomedical Signal Processing
  • Artificial Intelligence in Healthcare

Background:

  • Cardiac arrhythmias are a significant cause of morbidity and mortality.
  • Accurate detection and classification of arrhythmias are crucial for timely intervention.
  • Current methods often rely on complex analysis of full ECG signals.

Purpose of the Study:

  • To propose a knowledge-based method for classifying individual arrhythmic beats.
  • To develop a system for detecting and classifying arrhythmic episodes.
  • To utilize solely the RR-interval signal for these classifications.

Main Methods:

  • A three-RR-interval sliding window approach for beat classification.
  • Classification of four beat categories: normal, premature ventricular contractions, ventricular flutter/fibrillation, and 2nd-degree heart block.

    • The method was evaluated using the MIT-BIH arrhythmia database.
    • Achieved 98% accuracy for arrhythmic beat classification.
    • Achieved 94% accuracy for arrhythmic episode detection and classification.

    Conclusions:

    • The proposed method effectively classifies arrhythmias using only the RR-interval signal.
    • This approach offers a simplified yet high-performing alternative to more complex methods.
    • The results demonstrate the potential for efficient and accurate arrhythmia analysis.
