Arrhythmia and ST Analysis Troubleshooting
Excessive Electro-surgical
Interference
Wrong ECG cable used. Use ECG cable with internal filter
block.
NOTE: Respiration monitoring
via the ECG electrodes
will not be available
when using the cable.
Muscle noise.
Inadequate skin preparation
prior to application of
electrode, tremors, tense
subject, and/or poor
electrode placement.
Repeat skin preparation and
electrode location procedures.
Apply fresh, moist electrodes. Avoid
areas of the torso that are very
muscular.
Patient may have a
pacemaker that contains a
respiratory sensor.
Reposition electrodes to reduce ECG
artifact.
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.
Adjust alarm limits.
R-wave wrong size Must be twice the amplitude of the
other waves, like the P and T waves.
Excessive patient movement
or muscle tremor.
Reposition electrodes and secure
with tape, if necessary.
Low Amplitude ECG
Signal
Electrode could be positioned
over a bone or muscle mass.
Move ECG patches closer towards
each other.
Electrodes dry/old Apply fresh, moist electrodes.
Skin improperly prepared Abrade skin.
This could be the patient’s
normal QRS complex.
Verify with 12-lead
electro-cardiogram.
Gain set too low. Readjust the ECG wave gain as
required. Refer to the Wave Gain
Tab (System) for instructions on
adjusting the wave gain setting.
NOTE: Changing the ECG
wave gain does not
affect the arrhythmia
algorithm.
