Pacer (Pacer Version Only)
Symptom Recommended Action
15. “CHECK PADS” message.
• Ensure MFE Pads are connected to Multi-Function cable.
• Ensure electrode gel is not dry. Replace MFE Pads if
necessary.
• Ensure good electrode-to-patient contact.
• Check integrity of Multi-Function cable by plugging into test
connector. “CHECK PADS” should disappear.
16. No stimulus marker ( ) present on the ECG
trace.
• Ensure unit is in PACER mode.
• Ensure PACER RATE (ppm) is set greater than patient heart
rate.
17. No ventricular capture beat after stimulus marker on
ECG display.
• Check patient’s pulse.
• Increase output current.
• Ensure MFE Pads are making good contact with the patient.
• Select different ECG Lead configuration.
• Review MFE Pad placement.
18. Patient on “Standby” pacing gets paced
intermittently.
• Ensure proper ECG 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 rate.
• Verify rate is set appropriately
19. Heart rate display reads 0 with proper pacing
capture displayed on ECG trace.
• Check patient’s pulse.
• Select different ECG Lead configuration.
20. Bedside/Central Station/Telemetry ECG display
becomes erratic when pacing.
• Patient monitor ECG inputs overloaded by pacer signals.
ECG can only be monitored by the device while pacing.
