Adaptive algorithms may attenuate power line noise in ECG; leaves open effects on diagnostic accuracy or outcomes.
A novel signal processing model combining Discrete Wavelet Transform and Adaptive Noise Cancellation filters improves the denoising and recovery of true ECG signals.
Jagadesh et al. (2016) studied Electrocardiogram noise. Combined approach of Discrete Wavelet Transform (DWT) and Adaptive Noise Cancellation filter (ANC) was evaluated on Recovery of true ECG signals and tracking performance. A combined approach of Discrete Wavelet Transform and Adaptive Noise Cancellation demonstrated improved performance in recovering true ECG signals and better tracking performance.
