Follow-up Options
The pacemaker is equipped with an extensive array of automatic
functions that greatly simplify the adjustment and monitoring of the
pacing system and reduce the time required for follow-up
examinations. These functions include, for instance, automatic
interrogation of all programmed and memory data at the beginning of
the follow-up examination; the status window displays pacemaker
response at BOS (beginning of service) and ERI (elective replacement
indication, see the section on replacement indications for more details)
with and without a magnet applied, the date of the last follow-up
examination, and other information about the condition of the
pacemaker.
Note: Programming and additional information about the
individual functions are described in the technical
manual of the corresponding software module.
Realtime IEGM Transmission with Markers
The pacemaker offers the option of realtime transmission of the filtered
or unfiltered intracardiac electrogram (IEGM) to the programmer. The
filtered signal is used for the pacemaker timing. The programmable
settings relate to the filtered signal. Therefore only the filtered IEGM is
suitable for selecting a proper sensitivity setting. A simpler alternative
is to use the P/R-wave test to determine the amplitudes of the
intracardiac signal. In dual-chamber systems it is possible to transmit
and display the atrial and ventricular IEGM simultaneously. During
dual-chamber operation, the IEGM can be derived from the atrium and
ventricle simultaneously with a sampling rate of 5 to 60 Hz. If the IEGM
is derived either from the atrium or the ventricle, a sampling rate of 5
to 80 Hz is used.
