Pacing and Sensing Functions

Options for the ACC Function
The following options are available for the amplitude control function:
Active capture control
(ACC)
ON; OFF; A TM
ON
This option activates all sub-functions: The pacing threshold is
monitored and recorded, and the pacing energy is continuously
adapted. This is done with the following:
— Signal analysis
— Automatic pacing threshold search
— Verification of the stimulus response
ATM (Active
Threshold Monitoring)
Option
The threshold is monitored and recorded at programmable time
intervals. This is done with the following:
— Signal analysis
— Automatic pacing threshold search
Therefore, there is no continuous adaptation of the pacing amplitude.
OFF
This setting deactivates the entire amplitude control function.
Caution! When selecting the ATM or OFF options, make sure
that a sufficient safety margin is selected when
setting the pacing amplitude since there is no
automatic tracking of the pacing amplitude for
these options.
