Programmed to Triggered Modes
– When programmed to
triggered modes, pacing rates up to the programmed upper
limit may occur in the presence of either muscle or external
interference.
Triggered Modes
– While the triggered modes (DDT, VVT,
and AAT) can be programmed permanently, the use of these
modes is intended as a temporary setting in situations where
maintaining the programming head in place would be
impossible or impractical (i.e., during exercise testing or
extended Holter monitoring) or as a short term solution to
pulse generator inhibition by extracardiac interference. To
avoid the potential for early battery depletion, it is important
that the triggered modes are not used for long term therapy,
and that the pulse generator is returned to a non-triggered
permanent program.
7.2 Rate Related Functions
The availability of parameters and parameter values is
determined by the software used for programming/ interrogating
the pulse generator.
7.2.1 Basic Rate
The basic rate is the pacing rate in the absence of a
spontaneous rhythm and is programmable up to 200 ppm.

Programming Modifications – Extreme programming
changes
should only be made after careful clinical
assessment. Clinical judgment should be used when
programming permanent pacing rates below 40 ppm or above
100 ppm.
