Abstract

A method for high-resolution spectral analysis in multi-channel observations is disclosed with which it is possible to detect ventricular late potentials in individual heartbeats. The method also offers the basis for the spatial localization of pathological tissue modification that has a cause-and-effect relationship to the creation of these late potentials. The applicability of the method of the invention can be similarly applied to problems in radar or sonar technology, astronomy, measuring mobile radio telephone channels or to other problems of seismic or medical signal processing.
