Pacer
Symptom Recommended Action
1. CHECK PADS message
• Ensure therapy electrodes are connected to the
OneStep cable.
• Ensure electrode gel is not dry. Replace therapy
electrodes if necessary.
• Ensure good electrode-to-patient contact.
• Check integrity of OneStep cable by plugging into test
connector. CHECK PADS should disappear.
2. No stimulus marker ( ) is
present on the ECG trace.
• Ensure unit is in PACER mode.
• Ensure PACER RATE (ppm) is set greater than patient
heart rate.
3. No ventricular capture beat
appears after stimulus marker on
ECG display.
• Check patient’s pulse.
• Increase output current.
• Ensure therapy electrodes are making good contact
with the patient.
• Select different ECG Lead configuration.
• Review therapy electrode placement.
4. Patient on “Standby” pacing gets
paced intermittently.
• Ensure proper ECG electrode or OneStep Pacing/
Complete electrode connection and placement. If ECG
lead wire comes off, pacer will automatically pace
asynchronously.
• Check ECG cable for damage.
• Patient R-to-R interval varying. Pace rate close to
patient’s heart rate.
• Verify rate is set appropriately.
5. Heart rate display reads 0 with
proper pacing capture displayed
on ECG trace.
• Check patient’s pulse.
• Select different ECG Lead configuration.
6. Bedside/Central Station/Telemetry
ECG display becomes erratic
when pacing.
None, the patient monitor ECG inputs are overloaded by
pacer signals. ECG can only be monitored by the R Series
or pacing device while pacing.
