Pacemaker
40 Marquette Responder® 3000 227 490 02-C
Note
-
The default pacer rate can be configured.
-
If a defibrillation shock is triggered during
pacing, the pacemaker pauses automatically.
-
End the therapy as described under "Demand
Pacing" above.
Caution
Interrupted Arrhythmia Monitoring — Arrhyth-
mia monitoring is disabled while the pacemaker is
operating.
Fixed-Rate Pacing
Caution
: The pacer pulses are delivered via the
adhesive defibrillation electrodes which must be
applied as described in chapter 4.
Separate electrodes must be applied for acquisition
of the ECG signal (chapter 7).
The pacemaker can be enabled only when adhesive
electrodes are connected.
In fixed-rate mode, the device delivers pacing pulses
at the selected rate and current. The selected rate
remains constant and is not affected by intrinsic
actions of the patient's heart. This is the preferred
mode for cases of cardiac arrest.
•
Check that the ECG electrodes and the pace
pads are correctly applied and connected to the
device.
•
Press
On
Off
(
24
, Figure 6-1) to turn on the
pacemaker. The device defaults to the Demand
mode and selects a pacer rate of 60 P/min
(configurable).
•
Press the
Dem
Fix
button for 3 seconds to activate
the fixed-rate pacing mode (in the pacemaker
window on the screen, you will see "Fix"
instead of "Dem" (Figure 6-2).
•
Indicator
25
(Figure 6-1) goes off briefly with
each
delivered
pacing pulse.
•
Select the required pacer rate with
+ —
P/min
.
•
Now increase the pacer current output slowly
with
until the heart reliably responds to
the stimulation.
•
Verify the stimulation by watching the ECG on
the display.
•
Increase the pacer current output another 5 mA
to ensure continued stimulation.
