Application of Wavelet Entropy to Predict Atrial Fibrillation Progression from the Surface ECG
Figure 3
(a) ROC curve constructed from a specific learning set of the persistent AF patients. The WE value providing the highest accuracy was selected as optimum threshold, which has been marked with symbol . (b) Classification into ECV patients resulting in NSR and relapsing to AF for the corresponding validation set making use of the WE threshold obtained from previous ROC curve.
