PACE 203H – Instructions for Use

The DAI mode may be useful in situa-
tions where no ventricular sensing is
possible (for instance, because of inter-
ference), or when A-V synchrony must
be maintained upon a complete A-V
block.
9.6.9 The A-V Sequential, Ventricular
Inhibited (DVI) Pacing
A-V sequential, ventricular inhibited
(DVI) pacing provides pacing in both the
atrium and the ventricle but sensing only
in the ventricle. This mode is implicitly
selected by first setting the DDD mode,
and second, the atrial sensitivity to infi-
nite ("–.–"). Thus, sensing in the atrial
channel is disabled.
Note
: With the DVI mode (implicitly) set,
the following exceptions take place:
1) PACE 203H - specific algorithm for
determining extrasystoles is disa-
bled. In DVI mode, PACE 203H
cannot differentiate between high in-
trinsic rates and occurrences of
extrasystoles because the atrial
sensing is disabled.
2) If another R-wave is detected during
the V-A delay, the V-A delay will be
initiated with a value equal to the dif-
ference between the beat-to-beat in-
terval and the A-V Delay.
9.6.10 Atrial Sensing Atrial Synchro-
nous (P-Tracking) (VAT) Pacing
In atrial synchronous (P-tracking) (VAT)
pacing mode, PACE 203H stimulates
only in the ventricle but senses in the
atrium only. If intrinsic atrial activity oc-
curs, a ventricular stimulus is delivered
after the P-V delay.
This mode is implicitly selected by first
setting the VDD mode, and second the
ventricular sensitivity to infinite ("–.–").
Thus, sensing in the ventricular channel
is disabled.
The VAT mode may be useful in situa-
tions where no ventricular sensing is
possible (for instance, because of inter-
ference), or when A-V synchrony must
be maintained upon a complete A-V
block.
9.6.11 Non-Pacing Mode 0D0 (Pause)
In this mode, sensing is enabled in all
channels but not pacing. PACE 203H is
‘listening’ to intrinsic atrial and ventricular
events only.
The 0D0 mode is utilized to check the
patient’s intrinsic activity (see chapter
1.1) or to get initial values for the Auto
Sense feature (see chapter 9.9.4). It
must be used with
great caution
on
patients who are pacemaker dependent.
9.6.12 Atrial Trigger Modes AAT,
DDD+AT and DAT
If Atrial Trigger option (see chapter
9.12.5.3) is activated, an atrial stimulus
is delivered any time an atrial activity is
sensed, and with the atrial channel not
being refractory.
The Atrial Trigger is enabled when either
AAI (
→
AAT) or DDD (
→
DDD+AT) or
DAI (
→
DAT) modes are set.
