This study introduces a novel algorithm combining wavelet transform and morphological detection to improve electrocardiogram (ECG) waveform analysis. The new method enhances accuracy in detecting ECG swings, overcoming limitations of traditional wavelet transforms.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Cardiology

Context:

  • Electrocardiogram (ECG) analysis is crucial for diagnosing cardiac conditions.
  • Traditional wavelet transform methods face limitations in accurately detecting subtle ECG waveform features, particularly swings.
  • Existing algorithms may lack the precision required for robust ECG interpretation.

Purpose:

  • To develop an improved algorithm for ECG waveform detection.
  • To address the limitations of wavelet transform (WT) at level 3 for ECG analysis.
  • To enhance the accuracy and reliability of ECG signal processing.

Summary:

  • A novel algorithm is proposed, integrating wavelet transform (WT) with morphological peak and valley detection.
  • This combined approach compensates for the inherent limitations of WT in capturing ECG waveform amplitude variations.
