Wavelet analysis of cardiac optical mapping data
Optical mapping (OM) technology is important to study cardiac electrophysiology. Wavelet analysis offers simultaneous localization in time and frequency domains. Wavelet analysis improved the signal quality compared to Fourier-based filtering. Spatial wavelet filtering produced more accurate conduction velocity estimates. Wavelet analysis is a promising tool for OM electrophysiological characterization.
