1. A method of detecting and reverting pathological heart rhythms of a patient, comprising the steps of:
- sensing each of a plurality of electrical heart rhythm signals of the patient at two different locations;
calculating cross-phase spectra of sensed heart rhythm signals;
classifying the heart rhythms based upon information contained in said cross-phase spectra; and
,delivering appropriate therapy to the patient'"'"'s heart to revert heart rhythms classified as pathological.

Abstract
A method and apparatus for detecting and reverting pathological heart rhythms of a patient are disclosed. A plurality of electrical heart rhythm signals of the patient are sensed at two different locations within the heart. The cross-phase spectra of the sensed heart rhythm signals for each heartbeat are calculated and such heart rhythms are classified based upon the information contained in the cross-phase spectra. Appropriate therapy is then delivered to the patient'"'"'s heart to revert those of the heart rhythms that are classified as pathological.
