CLS Standby Mode
CLS Standby Mode is where, after auto-initialization, Closed Loop
Stimulation is fully installed but deactivated. When the implant is
interrogated for the first time, Closed Loop Stimulation can be
activated. The CLS Standby Mode entails the following:
— Closed Loop Stimulation has been installed, but is deactivated.
— Until CLS is activated, the implant will pace at the basic rate.
— During the first implant interrogation, the user can activate
Closed Loop Stimulation.
CLS is activated
Activating CLS after the first interrogation means the following
parameters have been set:
— DDD-CLS mode for dual-chamber implants or VVI-CLS mode for
single-chamber implants.
— AV delays and AV hystereses are automatically optimized for
CLS.
CLS is not activated
When Closed Loop Stimulation has not been activated after the first
follow-up, the following parameters are automatically set:
— DDD mode for dual-chamber implants or VVI mode for single-
chamber implants.
— The AV delays from the factory program are activated. AV
hystereses are turned off.
Programmable Parameters
In addition to activating and deactivating the entire function, the sub-
functions of lead detection can be activated individually.
Note: Patient data can always be configured regardless
of the auto-initialization function.
