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.
7.7.7 Rate Decrease
The rate decrease parameter determines the maximum rate of
change in the pacing rate, if the sensor signal indicates
decreasing exertion. In DDDR, VDDR, DOOR, VVIR, VOOR,
AAIR, and AOOR, the rate decrease setting of 0.5 ppm per
second decrease in pacing rate would take 180 seconds to
change from 150 ppm to 60 ppm.

The programmed rate decrease setting applies only to the
decrease in pacing rate during sensor-driven operation in the
primary chamber being paced.
