This study introduces a novel electrocardiogram (ECG) data compression method. It leverages the high correlation in ECG signals to achieve a better compression ratio (CR) than standard DCT methods.

Area of Science:

  • Biomedical Engineering
  • Signal Processing

Context:

  • Electrocardiogram (ECG) signals exhibit inherent regularity and periodicity.
  • This regularity leads to high correlations between Discrete Cosine Transform (DCT) coefficients of sequential ECG data frames.

Purpose:

  • To develop an advanced ECG data compression technique.
  • To improve upon existing DCT-based compression methods for ECG signals.

Summary:

  • The proposed method exploits the high correlation between DCT coefficients of consecutive ECG frames.
  • This approach results in a superior compression ratio (CR) compared to conventional DCT compression.

Impact:

  • Enhanced efficiency in storing and transmitting vital ECG data.
