If Smart Mode cancels a ventricular ATP therapy, you can either select a different therapy
or modify the current therapy settings to improve the therapy effectiveness. An ATP therapy
cancelled by Smart Mode is indicated by the label “Off-SM” on the VT/VF therapy counters
screen. For more information, refer to Section 9.2.5, “Evaluation of ventricular ATP
therapies”, page 377.
9.2.3 Programming considerations for ventricular ATP therapies
VT and FVT therapies – You should not use ATP therapies exclusively to treat VT or FVT
episodes. At least one VT therapy and one FVT therapy should be programmed to a
maximum energy cardioversion.
Cardioversion therapies for FVT – You cannot program all FVT therapies as ATP
therapies. If any FVT therapies are programmed on, at least one of the therapies must be
programmed to cardioversion therapy. The final FVT therapy must always be programmed
to cardioversion therapy.
Therapy aggressiveness – VT and FVT therapies must be programmed to be increasingly
aggressive. For example, you cannot program one VT therapy as cardioversion and a
subsequent VT therapy as a ventricular ATP therapy. Likewise, a VT cardioversion therapy
cannot be followed by another VT cardioversion therapy with a lower energy setting.
VF therapies – You cannot program VT and FVT therapies to On unless at least one VF
therapy is also programmed on.
Smart Mode – You can reset a ventricular ATP therapy cancelled by Smart Mode by
programming the Therapy Status parameter for that therapy to On. Smart Mode is not
available for the last two VT or FVT therapies.
9.2.4 Programming ventricular ATP therapies
The following programming steps apply to VT therapies, but you can program the FVT
therapies in the same way by selecting the Therapies… field for FVT on the Parameters
screen.
