摘要: An improved method of calculating magnitude-squared coherence spectra on pairs short-duration electrogram recordings is discussed. This based adaptive signal processing techniques and yields with higher resolution than those obtained using a straightforward direct method. The high-resolution will make it possible to examine the time-varying relationship between activity at two sites during atrial fibrillation may be useful for quick rhythm characterization by implanted devices or constructing maps in research studies. Example sinus rhythm, flutter, are presented.
