ECG Signal Maxima Detection Using Wavelet Transform

This paper deals with the application of a novel approach for ECG signal characteristic points detection by wavelet transform. The aim of this work is to detect automatically the R peaks, the T and P wave maxima, separately. After having represented the ECG equivalent in time frequency domain, we detect the complex QRS maximum and the T wave using the truncation of these waves by rectangular window. The influence of scale levels in our proposed algorithm is tested for a large amount of ECG signals. Results are given for signals extracted from the MIT/BIH database, confirming the robustness of our approach
