Abstract
A study of ventricular fibrillation and ventricular tachycardia was undertaken using wavelet-based multiresolution analysis. We adapted the analysis to a nonextensive (Tsallis) scenario on the basis of conventional Shannon entropy analysis of signals. It is shown that, as a criteria for detecting between VF and VT, Tsallis' multiresolution entropy (MRET) provides better discrimination power than the Shannon's multiresolution entropy (MRE) and this approach has great potentials in analyzing other nonstationary physiological signals.
