Originální abstrakt

The aim of this study was to analyse frequency components in electrograms (EGs) recorded from surface of isolated guinea pig hearts perfused according to Langendorff. Time-frequency analysis is based on algorithms Matching Pursuit and Wigner-Ville Distribution and its combination showing the energy density of the signal. The presented algorithms were tested on a set of electrograms, recorded during ischemia followed by reperfusion. The frequency components changed markedly during global ischemia experiments.
