Demand Test
The demand test checks that in the demand mode, the pacer will pulse
interactively with ECG waveforms at different rates. The demand test
requires that the pacer is in the demand mode and that the pacer ECG
monitor leads are connected to the ECG posts of the Impulse 4000.
Underdrive
The demand underdrive test checks to make sure the pacer outputs pacing
pulses when the ECG signal is too slow to sustain a patient without pacing.
The medTester displays the pacing rate and the underdrive ECG rate. Set the
pacer to demand mode at the pacing rate and turn on pacing. Press F5
START.
The medTester turns on the ECG waveform on the Impulse 4000.
The medTester indicates that pacing should be on. Observe the pacer ECG
monitor to check that the ECG signal is running and that pacing is on.
Press F4 PASS or F5 FAIL to store that with the record. FAIL is stored with
a “#”.
Overdrive
The demand overdrive test checks to make sure the pacer does not output
pacing pulses when the ECG signal is fast enough that the patient does not
need to be paced.
The medTester displays the pacing rate and the overdrive ECG rate. Set the
pacer to demand mode at the pacing rate and turn on pacing. Press F5
START.
The medTester turns on the ECG waveform on the Impulse 4000.
The medTester indicates that pacing should be off. Observe the pacer ECG
monitor to check that the ECG signal is running and that pacing is off.
Press F4 PASS or F5 FAIL to store that with the record. FAIL is stored with
a “#”.
