Async Test
The async test checks that in the asynchronous, or non-demand, mode, the
pacer will pulse correctly even with an ECG waveform at a high rate. The
async test requires that the pacer is in the async mode and that the pacer ECG
monitor leads are connected to the ECG posts of the Impulse 4000.
The medTester displays the pacing rate and the overdrive ECG rate. Set the
pacer to async 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.
During this test, the ECG signal and pacer activity could coincide.
Press F4 PASS or F5 FAIL to store that with the record. FAIL is stored with
a “#”.
Refractory Period Test
The refractory period test measures the refractory period of the pacer in the
demand mode. They are:
PRP Pulsed refractory period
SRP Sensed refractory period
Refer to the Impulse 4000 Operators Manual for definitions of the refractory
periods.
The refractory period 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.
Set the pacer to the demand mode and turn on pacing at the desired rate.
Press F5 START. Wait for the test to be completed.
When finished the medTester displays the test results: PRP, SRP, and pacing
rate. Press F5 CONTINUE to accept the results into the test record or F4
REPEAT to repeat the test.
