This study introduces a novel algorithm for real-time QRS complex detection in ECG signals using phase portraits. The algorithm achieves high accuracy, enabling effective cardiac event monitoring.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Cardiology

Background:

  • Accurate QRS complex detection is crucial for analyzing electrocardiogram (ECG) signals.
  • Traditional methods may face challenges with real-time processing and complex signal characteristics.

Purpose of the Study:

  • To develop and evaluate a new algorithm for real-time QRS complex detection in ECG.
  • To investigate the use of reconstructed phase portraits and delay-coordinate mapping for this purpose.

Main Methods:

  • Proposed a novel algorithm utilizing reconstructed phase portraits via delay-coordinate mapping.
  • Determined optimal mapping parameters (time delay=20 ms) using fill factor, mutual information, and autocorrelation.
  • Applied the algorithm to design a cardiac event recorder and tested on the MIT/BIH arrhythmia database.

Main Results:

  • The algorithm's performance was found to depend on the geometrical properties of the reconstructed phase portrait, specifically its area.
  • Achieved a high QRS complex detection rate of 99.58% on the MIT/BIH arrhythmia database.
  • Successfully implemented in a small cardiac event recorder for investigating heart rate variability (HRV) in patients with vasovagal syncope.

Conclusions:

  • The proposed phase portrait reconstruction method offers an effective approach for real-time QRS complex detection.
  • This algorithm has practical applications in developing compact cardiac monitoring devices for diagnosing conditions like vasovagal syncope.
