Abstract

Techniques for discrimination of heart rhythms in cardiac rhythm management devices include determining a current covariance matrix of multiple electrograms measuring each current heart beat, determining a distance measure between the current covariance matrix and a predetermined covariance matrix of the multiple electrograms measuring at least one different heart beat; and determining whether the heart beat represents ventricular tachycardia based on the distance measure.
