Table 11: Rate Increase
In DDIR and DVIR, the rate increase is slightly slower than indicated here (depending on the
programmed AV interval). The programmed rate increase setting applies only to the increase in
pacing rate during sensor-driven operation and does not affect the pacing rate during atrial triggered
ventricular pacing.
5.7.5 Maximum Sensor Rate
Figure 29: Gain Setting Choices
Regardless of the sensor signal strength, the pacing rate during sensor-driven operation will never
exceed the programmed maximum sensor rate. The maximum sensor rate only limits the pacing
rate during sensor-driven operation and is independent of the rate limit. The maximum sensor rate
(programmable up to 180 ppm) must be less than or equal to the programmed UTR.
NOTE:
In the DDIR and DVIR modes, the sensor rates control the ventricular pacing rates independent of
the AV Delay.
5.7.6 Maximum Closed Loop Rate
With the Evia CRT-P programmed to CLS rate adaptation, the pacing rate during CLS-driven operation
will never exceed the programmed maximum closed loop rate. The maximum closed loop rate only
limits the pacing rate during sensor-driven operation and is independent of the rate limit. The maximum
closed loop (programmable up to 160 ppm) must be less than or equal to the programmed UTR.
CAUTION
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.
