Rate and Sensor Trend
The rate trend is a real-time trend, whereas the sensor trend is a
simulated trend.
Sensor Trend with Rate Forecasting
Valid for Cylos
The pacemaker can record the sensor rate curve over a period of 12
minutes to optimize sensor rate settings. The resolution is four
seconds. Recording stops automatically after 12 minutes.
After the sensor trend has been recorded, the rate forecast function
can simulate various settings for every parameter that influences the
rate (for example sensor gain, sensor threshold, maximum activity
rate, basic rate, etc.).
This makes it easier to optimize rate-adaptive parameters, since
repeated exercise tests are no longer necessary.
Note: With sensor simulation you can only select values
of the sensor threshold that are greater than those
used in the permanent program.
High-Resolution Threshold Test
For facilitating follow-up, the pacemaker features a high-definition
threshold test with a resolution of 0.1 V in the range of 0.1 to 4.8 V.
The test is activated as a temporary program. Lifting the programming
head or pressing the key terminates the threshold test and makes the
pacemaker immediately revert to the permanent program.
During the threshold test, the pacing rate should be higher than the
spontaneous rate to avoid competitive pacing.
