The detection architecture of the present invention provides methods and devices for discriminating between arrhythmias. Moreover, by exploiting the enhanced 5 specificity in the origin of the identified arrhythmia, the detection architecture can better discriminate between rhythms appropriate for device therapy and those that are not. 3888680_1 (GHMatters) P59082.AU.2 17/12/121/30 20 V2 FIG2l ~ ~ ~ 'N. 16 FIG. 1A. s A 36. . . ~ ' 11.1.
