Patent ID: 6909916

Claim:
A cardiac rhythm management system including: a plurality of electrodes, sized and shaped to be associated with a heart; a cardiac signal detector circuit, coupled to the electrodes; an energy output circuit, coupled to at least one of the electrodes; and a controller, coupled to the cardiac signal detector and the energy output circuit, the controller including: an arrhythmia detector module to detect an arrhythmia; an arrhythmia classifier module, to classify the detected arrhythmia into an arrhythmia classification that specifies at least a sequence in which a heart contraction depolarization is received by at least three of the electrodes during the arrhythmia; a therapy map, providing an antiarrhythmia therapy corresponding to the arrhythmia classification; and a control signal to be issued to the energy output circuit to deliver a selected antiarrhythmia therapy corresponding to an arrhythmia classification.
