Performance Analysis of Multiscale Entropy for the Assessment of ECG Signal Quality

Figure 5

The results of SNR effect on the MSE for the artificial signals. (a) The 3D view of the relationship between MSE and SNRs of the clean ECG plus LF noise. (b) Examples of the clean ECG plus LF noise with SNRs of −10 dB, 0 dB, or 10 dB, as well as the clean ECG. (c) The 3D view of the relationship between MSE and SNRs of the clean ECG plus HF. (d) Examples of the clean ECG plus HF with SNRs of −10 dB, 0 dB, or 10 dB, as well as the clean ECG. (e) The 3D view of the relationship between MSE and SNRs of the clean plus PL. (f) Examples of the clean plus PL noise with SNR of −10 dB, 0 dB, or 10 dB, as well as the clean ECG.
