The ECG-dedicated compression method using high frequency patterns
Piotr Augustyniak · 2000
This work deals with the problem of effective and lossless ECG compression. The proposed method uses pre-processed signal with delimited startand endpoints of P, QRS and T-waves. Our method searches for nonspecific patterns of time-frequency coefficients in highest three octaves in the P-QRS-T region. High compression ratio is obtained for long signals mainly (e.g. Holter recordings) due to sending or storing one pattern number per beat instead of the whole set of coefficients.
