The Difference Operation Method (DOM) accurately detects the QRS complex in electrocardiogram (ECG) signals. This novel approach offers precise detection rates and faster processing speeds compared to existing methods.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Cardiology

Background:

  • Electrocardiogram (ECG) signal analysis is crucial for diagnosing cardiac conditions.
  • Accurate detection of the QRS complex is fundamental for automated ECG interpretation.
  • Existing QRS detection methods face challenges in precision and speed.

Purpose of the Study:

  • To introduce a simple and reliable method for QRS complex detection in ECG signals.
  • To evaluate the performance of the proposed method against established techniques.

Main Methods:

  • The Difference Operation Method (DOM) was developed, comprising two stages.
  • Stage 1: Identifies the R-point using a difference equation operation on the ECG signal.
  • Stage 2: Locates Q and S points relative to the R-point to define the QRS complex.
