ABSTRACT:
A system and method evaluates the spatial organization of atrial activation sequences of a heart. Electrical activity of an atrium is sensed at a predetermined number of different localized locations within the atrium to generate a like predetermined number of electrograms. The electrogram generated for each localized location is cross-correlated with the electrograms generated for every other localized location to derive a set of correlation values. A space constant derivable from the correlation values or the correlation values themselves may be used to evaluate antiarrhythmic drug effectiveness or, within an implantable atrial defibrillator, atrial arrhythmia type.
