vPad-XSC for Impulse 4000 USER MANUAL
Task: Wait! Then verify pacer pulse test result
Data: Pacemaker Pulse Test:
Acceptable Limits Results
Current: 30 mA +/- 10 % 29.8 mA
Rate: 70 PPM +/- 2 PPM 70.1 PPM
Width: --- ms +/- --- 18.27 ms
Result: PASS
___________________________________________________________
A placeholder "- - -" appears in the test data whenever a target is not specified or a limit is not
enabled.
3.4.2 Pacemaker Refractory Period Test
To perform a pacemaker refractory test, use a vPL statement of the form
xtest"< instr >" | PRF< fmt >
where:
< instr >
is an instruction to be displayed to the user while the refractory test is in progress,
PRF
is the command to measure pacer refractory period, and
< fmt >
can be either “
S
” or “
L
”, as there is only one test result format.
Impulse 4000
measures two pulse characteristics for this test: the paced refractory period (PRP) and the
sensed refractory period (SRP). Since the only limit types allowed for both measurements are “
min
”,
“
max
”, and “
range
”, no target is needed in the “
xtest
” statement. Results are automatically passed or
failed after pacer PRP and SRP limits have been enabled.
3.4.2.1 Example 12: Measuring Pacemaker Refractory Period
A Checklist may start a pacemaker refractory test with automatic pass/fail through vPL statements
similar to the following:
xctrl “Setting PRP limit: 200 to 500ms" | lim8,range,200,500
