Rate Adaptation

Maximum Activity Rate
Regardless of the sensed amplitude of the sensor signal, the pacing
rate will not exceed the programmed maximum activity rate (see Figure
21).
The programmed value applies only to the maximum pacing rate
during sensor-controlled operation and is independent of the upper
tracking rate.
Figure 21: Maximum activity rate
Note: In the DDIR and DVIR modes, lower maximum
sensor rates result than those indicated here,
depending on the selected AV delay. The correct
values are indicated by the programmer.
The shorter the selected AV delay is, the higher the
maximum sensor rates can become.
Rate Decrease
The value programmed for the rate decrease determines the maximum
speed by which the pacing rate is reduced when there is a fading
sensor signal (see Figure 22).
