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.
