This study introduces a novel double-sliding-window technique for real-time electrocardiogram (ECG) anomaly detection. The method offers efficient and accurate identification of heart rhythm deviations with minimal computational resources.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Cardiology

Background:

  • Traditional anomaly detection in ECG signals is often computationally intensive.
  • Existing methods may require prior data distribution knowledge or fixed thresholds, limiting real-time application.
  • Machine learning models can be resource-heavy for embedded or portable systems.

Purpose of the Study:

  • To develop an efficient and adaptive anomaly detection technique for ECG signals.
  • To enable real-time heart rhythm deviation identification without prior data assumptions.
  • To assess the performance of a novel double-sliding-window method.

Main Methods:

  • A double-sliding-window approach was implemented for adaptive signal analysis.
  • Two independent sliding windows dynamically tracked ECG signal variations.

  • The system was evaluated for computational efficiency (execution time, memory usage) and detection accuracy.

    • Main Results:

    • The detection module demonstrated an average execution time of 0.03 seconds and used less than 16 MB of memory.
    • Achieved high performance metrics: 95.33% accuracy, 95.00% sensitivity, 100.00% precision, and 100.00% specificity.
    • The method proved suitable for real-time systems due to its low resource requirements.

    Conclusions:

    • The double-sliding-window technique provides an efficient and accurate solution for ECG anomaly detection.
    • This adaptive method is well-suited for real-time applications, including portable and resource-constrained devices.
    • The study highlights the potential of dynamic signal analysis for improved cardiac monitoring.
