ECG Monitoring Problems
TIP: When troubleshooting problems with paddles or pads, try replacing the paddles or pads first.
When troubleshooting ECG problems, try replacing the ECG cable first.
Table 15 Pacing Problems
Symptom Possible Cause Suggested Solution
Does not deliver correct current into
pacer tester or delivers no current at all
Therapy PCA failure • Run Op Check
• Inspect the Hardware Error Log
• Replace Therapy PCA

• Replace Therapy Port
Processor PCA failure (if using ECG
Leads)
Replace Processor PCA
Therapy PCA failure (if using Pads) Replace Therapy PCA
Poor ECG signal quality – (noisy
trace, wandering baseline, etc.)
from signal acquired from
monitoring electrodes.
Poor skin preparation or electrode
contact
Ensure that the user is properly connecting
electrodes and preparing patient’s skin
Radio frequency interference (RFI) is
causing artefact
Relocate or turn off equipment that may be
causing RFI
