Mode switching is initiated in atrial tracking modes when the atrial
rate, defined by the programmable mode switch Intervention
Rate is achieved. However, mode switching will not occur until
the Mode Switch Onset Criterion is also met. The activation
criterion is a programmable X out of 8 high rate intervals as
programmed. RVsense Triggering can be programmed
separately during mode switching.
After switching to a non-atrial tracking mode, the ICD/CRT-D
activates a Y out of 8 counter that deactivates mode switching
when Y number of cardiac cycles out of the last 8 are below the
Intervention Rate. When this Resolution Criterion parameter is
fulfilled, the ICD/CRT-D returns to the normal programmed pacing
mode.
In addition, the ventricular pacing configuration (RV or BiV) and
biventricular pacing parameters (LV T-wave protection and
Triggering) are programmable separately for mode switching
events.
2.9.8.1 Mode Switch Basic Rate
Whenever Mode Switching occurs, the device switches to a non-
tracking mode and will provide bradycardia pacing support at the
Mode Switch Basic Rate, which is displayed as the Change of
Basic Rate parameter. Once Mode Switching is
terminated, the
permanently programmed pacing mode and programmed pacing
rate are restored.
