Sample Entropy Analysis of Noisy Atrial Electrograms during Atrial Fibrillation

Table 1

SampEn statistical characteristics for both classes NC AEGM and C AEGM when a spike train of probability is added. For each , the statistical probability related to the separability between classes (-value), the confidence intervals (CI) at 95%  , and the cross correlation coefficient between the SampEn values of the initial signal and the signal corrupted with spikes are given.
