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

Figure 6

The validation results of SNR effect on MSE for the real ECG signals. (a), (c), (e), and (g) are the 3D view of the MSE of the real ECG plus BW, EM, MA, and PL, with SNR from −20 dB to 40 dB with a step of 10 dB, respectively. (b), (d), (f), and (h) are the MSE values of the noisy ECGs with −10 dB, 0 dB, 10 dB, and the real ECG, respectively.
