Abstract: A novel algorithm for ST-segment analysis is developed using the multiresolution wavelet approach. The algorithm has been implemented on a TMS320C25 based add-on DSP card to a PC to provide the on-line analysis and display of ST-segment data. The performance of the system is evaluated using standard ECG waveforms with different morphologies and heart rates in order to take into account the variability of the data encountered in the clinical environment. The results show that the average errors in the calculation of the ST-segment with different morphologies at heart rates of 60 BPM and 120 BPM are 2.0% and 3.3%, respectively. These errors are well within acceptable limits for clinical use. The proposed algorithm has great potential to be a part of an integral ECG analysis system
