Follow-up Basics
Follow-up lets you check the pacing system and optimize settings.
The likelihood of an electronic defect or a premature battery depletion
is extremely low. Pacing system malfunctions attributed to other
causes such as threshold increase are considerably more probable. In
most instances, they can be corrected by reprogramming the
pacemaker. The follow-up intervals are, therefore, primarily determined
by medical considerations, taking into account the patient's
dependency on the pacemaker.
The following notes are meant to stress certain product features of the
pacemaker that are of importance for the follow-up. For detailed
recommendations on the performance of follow-up tests and medical
considerations, please refer to the pertinent medical literature.
See the respective software module manual for a detailed description
of the procedure and for more information on the individual functions.
Note: Only ECG devices that do not delay the display of
the ECG curve should be used for pacemaker
follow-up. Devices with such a delay (e.g., devices
with automatic base line adjustment) are
fundamentally unsuitable for pacemaker follow-up.
Battery Status
The replacement indication is reached when the pacing rate without
magnet application is 4.5 – 11% lower than the programmed basic
rate (depending on the selected mode).
