The ECG-dedicated compression method using high frequency patterns

This paper deals with the problem of effective and lossless ECG compression. The proposed method uses pre-processed signals with delimited start- and end-points of the P, QRS and T-waves. Our method searches for non-specific patterns of time-frequency coefficients in the highest three octaves in the P-QRS-T region. High compression ratios are mainly obtained for long signals (e.g. Holter recordings), due to sending or storing one pattern number per beat instead of the whole set of coefficients.
