9.9.4.4 Notes for the Initialization of
the Auto Sense function
If the user continues to press the softkey
labeled
Initiate
, PACE 203H will continue
to search for intrinsic activity and find the
optimal value.
If PACE 203H detects frequencies high-
er than the noise frequency (270 ppm)
during the Auto Sense initialization, the
corresponding interference symbol
(Figure 13) is shown in the upper dis-
play. Any P or R wave value determined
by PACE 203H during interference is
cleared off the display. 2 seconds after
PACE 203H determines interference
with the Auto Sense function enabled,
the sensitivity setting will be doubled in
order to find a sensitivity level where the
heart activity is sensed without interfer-
ence.
If no activity is sensed in a channel for
3 seconds, a previously determined P or
R wave will be cleared off the display.
Table 26 shows an example were an
atrial rhythm could be found, but no
ventricular rhythm.

If no intrinsic rhythm is detected in one
or both channels, the respective check
mark continues blinking after returning to
the previous menu. The initialization
request persists as shown in Table 27.
