摘要：

A new non-invasive technique is presented for the characterization of time-dependent spectral properties of atrial fibrillation in the surface EGG. The method uses the Wigner-Ville distribution for time-frequency analysis and the cross Wigner-Ville is used to compute trends which describe the instantaneous frequency of the atrial activity. Preliminary results indicate that short-term variations exist in the fibrillation cycle lengths and that the variations can exhibit similar behavior in the leads V-1-V-3.
