This study introduces a novel histogram analysis for rapid ECG analysis, distinguishing between normal heartbeats and atrial fibrillation (AF). The method reliably detects P-waves or f-waves, simplifying AF diagnosis.

Area of Science:

  • Biomedical Engineering
  • Cardiology
  • Signal Processing

Background:

  • Electrocardiogram (ECG) analysis is crucial for diagnosing cardiac conditions.
  • Atrial fibrillation (AF) presents unique challenges in ECG interpretation.
  • Existing methods for AF detection can be complex or time-consuming.

Purpose of the Study:

  • To develop a rapid and reliable method for detecting QRS-T complexes in ECGs.
  • To accurately identify the presence or absence of atrial fibrillation (AF) by detecting P-waves or f-waves.
  • To differentiate between normal sinus rhythm and AF using signal processing techniques.

Main Methods:

  • Utilized histogram analysis for ECG signal processing.
  • Applied fractal dimension and Shannon entropy methods for signal characterization.

Related Experiment Videos

  • Analyzed ECG signals from subjects with and without AF.

    • Main Results:

    • Significant differences were documented between ECG signals with and without AF.
    • The histogram analysis approach demonstrated high reliability in detecting QRS-T complexes.
    • The methods effectively distinguished between the presence and absence of AF.

    Conclusions:

    • The proposed histogram analysis offers a fast and dependable approach for ECG interpretation.
    • This technique simplifies the detection of atrial fibrillation, improving diagnostic efficiency.
    • The study validates the utility of fractal dimension and Shannon entropy in AF identification.
