Lead Placement Troubleshooting
4.5 Troubleshooting
This section lists some of the potential messages and issues that may occur.
MESSAGE/ISSUE * REASON SOLUTION
Noisy ECG traces Loose or dry electrodes. Apply fresh, moist electrodes.
Defective electrode wires. Replace wires as necessary.
Patient cable or leads are
routed too close to other
electrical devices.
Eliminate 60 Hz interference.
Use ECG cable with internal filter
block.
Excessive Electro-surgical
Interference
Inadequate skin preparation
prior to application of
electrode.
Repeat skin preparation and
electrode location procedures.
Apply fresh, moist electrodes.
Intermittent Signal Connections not tight and/or
properly secured.
Ensure proper connection. (cable to
monitor, cable to lead, lead to
electrode).
Electrodes dry or loose. Repeat skin preparation and apply
fresh, moist electrodes.
Cable or lead wires
damaged.
Check with continuity tester.
Excessive alarms: heart
rate, lead fault
Electrodes dry Repeat skin preparation and apply
fresh, moist electrodes.
Alarm limits set too close to
patient's normal heart rate.
Readjust
R-wave wrong size Must be twice the amplitude of the
other part of the waveform.
Excessive patient movement
or muscle tremor.
Reposition electrodes and secure
with tape, if necessary.
Low Amplitude ECG
Signal
Gain set too low. Readjust the ECG wave gain as
required. Refer to the ‘‘Wave Gain
Tab (System)’’ on page 9-44 for
instructions on adjusting the wave
gain setting.
Electrodes dry/old Apply fresh, moist electrodes.
Skin improperly prepared Abrade skin.
Possibly not patient's normal
complex.
Check with 12-lead electro-
cardiogram.
Electrode could be positioned
over a bone or muscle mass.
Reposition electrodes.
No ECG Waveform Gain set too low. Readjust the ECG wave gain as
required. Refer to the ‘‘Wave Gain
Tab (System)’’ on page 9-44 for
instructions on adjusting the wave
gain setting.
Lead wires and patient cable
not fully inserted into proper
receptacle.
Check insertion.
Cable or lead wires
damaged.
Check with lead continuity tester.
