ECG's QRS Peak Detection and Heart Rate Estimation using Discrete Wavelet Transform (DWT) in MATLAB

a scheme is presented to detect QRS complex (R-Peaks) of an ECG signal using un-decimated Discrete Wavelet Transform (DWT). It is shown that how band pass filtering of ECG signal is achieved to preserve R-peaks using DWT which is superior than frequency selective BPF. Also by counting total number of R-peaks, Heart Rate (in beats per minute) is  calculated. Also robustness of the proposed scheme is shown on different types of ECG signals taken from MIT-BIH arrhythmia and ECG-ID databases from PhysioNet.
