Discriminators for @entity1165 . INTRODUCTION: Dual-chamber @entity737 ( @entity737 ) use discriminators to differentiate between @entity4710 ( @entity4710 ) and @entity1165 ( @entity1165 ), the accuracy of which may depend on the type and method used. @entity737 can combine rate branching of @entity591 according to their A:V relationship with two @entity1165 in each rate branch, using ANY (either) or @entity981 (both) logic. Our goal was to determine the optimal discriminator combination. METHODS: Stored electrogram data from 596 spontaneous @entity591 from 203 @entity1 with Photon DR @entity737 were analyzed. @entity943 are first classified by the relationship of @entity2224 (rate branches V<A, V=A, and @entity68142 ) followed by additional discriminators: morphology and/or sudden onset if V=A; morphology and/or interval stability if V<A. Data were analyzed for all combinations of ANY and @entity981 logic. RESULTS: Sensitivity and specificity were calculated for all spontaneous episodes in each analysis. V=A branch: @entity981 logic produced unacceptably low sensitivity, whereas morphology provided only similar sensitivity but better specificity than ANY logic. A>V branch: ANY logic provided adequate sensitivity. The combination of morphology only in V=A with interval stability or morphology (ANY logic) in V<A, provided the optimal result with sensitivity, specificity, positive, and negative predictive values of 99%, 79%, 87%, and 98%, respectively. CONCLUSION: SVT- @entity1165 combined discriminators strongly influence dual-chamber SVT- @entity1165 discrimination performance. In our study, optimal programming is morphology only in the V=A branch and morphology or interval stability (ANY) in the V<A branch. @entity981 logic should be used with caution due to loss of sensitivity.
