| Abstract: | In this paper is presented a new ECG signal detection algorithm, which combines amplitude maximum of ECG details of Harr wavelet transform decomposition at 3 level with mathematical morphology max min(peak trough) detection, and ECG wavelet transform algorithm is proposed. This algorithm improves the accuracy of detection of time domain features when wavelet transform algorithm is used. |
