Optional Quality Control of ECG Data Compression Algorithm

The paper proposes an efficient ECG signal compression algorithm with high fidelity. It encodes the data with jpeg2000 algorithm and improve on partial data loss when the signal data are transformed to 2-dimension. The algorithm contains: QRS detection, signal pre-estimate and classification, 2-dimension conversion, signal compression encoding, signal rebuilding and algorithm evaluation. Compare with universal evaluation criterion of ECG algorithm items, its performance is better than others and keep most information for diagnosis.
