Conducting a Temporary Parameter Test
The waveform display lets you view the patient’s ECG and the telemetered
waveforms while you are testing temporary parameter settings. Refer to
pages 5-6 and 5-7 for information about the waveform display and its
control buttons.
WARNING: High-rate stimulation of the ventricles could result in
ventricular tachycardia or fibrillation. Application of temporary high-rate
pacing should be performed only under careful patient monitoring and
control.
Use the following procedure to program temporary parameter values. Refer
to the table on the next page for parameter information.
1. If the pacemaker is a dual chamber model, select the desired test
chamber.
2. Use the [∧
∧∧
∧] or [∨
∨∨
∨] button to select the desired test mode.
3. Using the [∧
∧∧
∧] and [∨
∨∨
∨] buttons, select the desired test parameter values.
4. Position the programming head; press and hold [
PROGRAM
] for as long
as you want the test parameter to be in effect. The test values in effect
will show on the screen.
5. To end the test, release [
PROGRAM
].
A Note About Hysteresis
If Hysteresis has been programmed to ON during previous use of the AAI,
AAT, VVI, or VVT pacing mode, it will be in effect when ever you return
to one of these modes — even during temporary parameter testing. If a
message indicates that Hysteresis is in effect, you can program it to OFF by
returning to the Pacing Parameters screen. To access Hysteresis, you must
select one of the single chamber modes mentioned above.
