Rate Adaptation

Sensor Gain
The sensor gain designates the factor by which the electric signal of
the sensor is amplified before subsequent signal processing occurs.
The programmable sensor gain permits adaptation of the desired rate
adaptation to the individually variable signal strengths. The optimum
setting is achieved when the desired maximum pacing rate is attained
during exertion (see Figure 17).
Before adjusting the sensor gain, the rate increase, rate decrease, and
maximum sensor rate parameters must be checked for their suitability
with respect to the individual patient.
If the rate increase is not sufficient during high levels of physical
exertion, the sensor gain should be increased. On the other hand, the
sensor gain should be reduced if high rates are obtained at low levels
of exertion.
Note: Apart from the manual adjustment of the sensor
gain, an automatic sensor gain function is available
(see the "Automatic Sensor Gain" section).
