Cardiac rhythm management system with arrhythmia classification and electrode selection
First Claim
1. An implantable cardiac rhythm management device for coupling to a plurality of electrodes for association with a heart, the device including:
- a cardiac signal detector circuit, for coupling 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;
(a) a sequence in which a same heart contraction depolarization is received by at least three of the electrodes, wherein at least two electrodes are associated with different heart chambers, and (b) values of relative interelectrode time that the same heart contraction depolarization is received by the three electrodes;
a therapy map, providing an antiarrhythmia therapy corresponding to the arrhythmia classification, wherein an antiarrhythmia therapy is delivered according to an electrode sequence that is mapped to the relative interelectrode time; and
a control signal to be issued to the energy output circuit for delivering a selected antiarrhythmia therapy corresponding to an arrhythmia classification.

Abstract
A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification.
