PACE 203H – Instructions for Use

With alarms enabled, pressing the
softkey labeled
Alarms
causes the check mark to disappear
from the corresponding check box. In the
upper display, the crossed bell symbol
(see Figure 8) is shown.
Figure 8: Alarms Off (Crossed Bell)
Symbol
To reactivate the lead surveillance fea-
ture and the protection against abnormal
settings, the Alarms key must be
pressed again. This causes the check
mark to appear in the corresponding
check box, and the crossed bell symbol
in the upper display disappears.
Note:
If previously disabled Alarms are
enabled, PACE 203H will solve possible
conflicts caused by abnormal settings
using its Automatic setting feature. The
fact that PACE 203H adapted a parame-
ter to the set Basic Rate is indicated by a
message temporarily shown in the lower
display (see chapter 9.22.7 and 9.9).
9.12.5.3 Enable and Disable Atrial
Trigger Function
When the atrial trigger function is ena-
bled, PACE 203H delivers an atrial stim-
ulus immediately after an atrial sensing
within the atrial sensing phase.
With the softkey labeled
Atrial Trigger
in the Options Menu, the atrial trigger
function can be enabled or disabled. In
case the atrial trigger function is ena-
bled, the corresponding check box is
checked. Furthermore, PACE 203H
indicates the label
A-TRIG
in the atrial
stimulation section of the upper display.
Note:
The atrial trigger function is avail-
able in the primary modes AAI and DDD.
To turn the atrial trigger function off, the
softkey labeled
Atrial Trigger
must be
pressed again. The check mark disap-
pears from the corresponding check box,
and the label
A-TRIG
disappears from
the upper display as well.
Atrial Trigger is also disabled when the
primary mode is changed to VVI or VDD,
because these modes do not provide
atrial stimulation. Atrial Trigger must be
activated again after changing back to
the primary modes AAI or DDD.
Note:
Atrial Trigger cannot be used in
conjunction with Atrial Auto Sense, be-
cause the triggered stimulation prevents
proper measurement of the intrinsic atrial
activation. (see also 9.9.4).
Note:
A sensed atrial event in the rela-
tive PVARP (see chapter 9.12.1) is nev-
er followed by a (triggered) atrial stimula-
tion – even if atrial trigger is enabled –
because it may be a ventricular echo.
