Does the WHAT algorithm improve R peak detection in ECG signals compared to other techniques?
The proposed WHAT algorithm, combining wavelet and Hilbert transforms with adaptive thresholding, improves R peak detection in ECG signals.
Rabbani et al. (2011) studied ECG signal processing (R peak detection). WHAT algorithm (Wavelet Transform, Hilbert Transform, Adaptive Thresholding) vs. HAT, WAT, and HWAT algorithms was evaluated on R peak detection at various noise levels (SNR). The WHAT algorithm successfully detected R peaks in ECG signals at noise levels down to -5 dB, outperforming HAT, WAT, and HWAT methods.
