96 Stratos LV/LV-T Technical Manual
The following diagnostic functions are available to tailor rate
adaptive pacing for the individual patient.
2.14.2 Sensor Gain
The sensor gain defines the slope of the linear function between
exertion and pacing rate. It designates a factor by which the
electric signal of the sensor is amplified prior to the signal
processing stages. The programmable amplification permits
adaptation of the individually programmed sensor gain to the
desired rate response. The optimum setting is achieved when
the desired maximum pacing rate during exertion is reached
during maximum exercise levels. The rate increase, rate
decrease and maximum sensor rate settings must be checked
for their suitability with respect to the individual patient before
adjusting the sensor gain.
If the sensor-driven rate is not sufficient at high levels of exertion
the sensor gain setting should be increased. The sensor gain
should be reduced if high pacing rates are obtained at low levels
of exertion (see Figure 6
).

2.14.3 Automatic Sensor Gain
Stratos CRT-Ps offer an Automatic Sensor Gain setting, which
allows the physician to have the Sensor Gain parameter
adjusted automatically.
