Spectral validation improves frequency tracking obtained by time-frequency analysis during atrial fibrillation

Abstract

The fibrillatory frequency trend and the time-dependent spectral characteristics can be investigated using a spectral profile technique in patients with atrial fibrillation (AF). The aim of this study is to develop model-based means for stricter control on the update of the spectral profile. A spectral model defined by Gaussian functions is suggested for… (More)
