Muscle or Nerve Stimulation
– Inappropriate muscle or nerve
stimulation may occur with unipolar pacing when using a non-
coated pulse generator.
CLS Rate-Adaptation
– Under certain circumstances (e.g., EMI,
lead dislodgment), the Evia device may not be able to obtain a
useable impedance measurement as required for CLS
rate-adaptive pacing. At this point, CLS rate-adaptation will be
inactive until the situation is corrected. Rate-adaptation may be
programmed to switch to motion based adaptation.
Programmed to Triggered Modes
– When programmed to
triggered modes, pacing rates up to the programmed upper limit
may occur in the presence of either muscle or external
interference.
Triggered Modes
– While the triggered modes (DDT, VVT, and
AAT) can be programmed permanently, the use of these modes
is intended as a temporary setting in situations where
maintaining the programming head in place would be impossible
or impractical (i.e., during exercise testing or extended Holter
monitoring) or as a short term solution to pulse generator
inhibition by extracardiac interference. To avoid the potential for
early battery depletion, it is important that the triggered modes
are not used for long term therapy, and that the pulse generator
is returned to a non-triggered permanent program.
4.5 Home Monitoring
BIOTRONIK’s Home Monitoring system is designed to notify
clinicians in less than 24 hours of changes to the patient’s
condition or status of the implanted device. Updated data may
not be available if:
•
The patient’s CardioMessenger is off or damaged and is
not able to connect to the Home Monitoring system through
an active telephone link.
•
The CardioMessenger cannot establish a connection to the
implanted device.
•
The telephone and/or Internet connection do not operate
properly
