ECG Problem Solving
If ECG signal quality is poor (indicated by wandering baseline, excessive noise, or muscle or
respiration artifact), try the solutions from the list that follows:
Make sure that silver/silver-chloride electrodes are being used.
Make sure that the patient's skin is properly prepared.
Make sure that all electrodes are firmly attached and in good condition.
Make sure that the electrodes are positioned on a flat, non-muscular area.
Make sure that leadwires are properly fastened and in good condition.
If these actions fail to resolve the problem, select a different lead.
Lead Fault Indication
The lead fault indication messages listed here are on the central monitor/station and not the transmitter
display.
The message CHECK XX (where XX identifies the failed or missing electrode) appears in the ECG
waveform zone if a lead fault occurs.
If automatic lead switching is enabled, another lead is automatically selected so that monitoring is
uninterrupted.
A LEADS OFF message appears if automatic lead switching is disabled.
Noise Detection
A NOISY SIGNAL message appears in the ECG waveform zone of the central monitor/station if noise
is detected. If both the first and second lead are noisy, the module suspends processing temporarily. If
the noise persists for 10 seconds, the system initiates an alarm. The message and alarm cease when
the noise disappears.
Notes:
If monitoring is interrupted because of overload or saturation of the input amplifiers,
including overload caused by a defibrillator discharge, the ECG waveform is shown as an
out-of-range signal accompanied by a NOISY SIGNAL or HR UNAVAILABLE message.
If the overload or saturation condition persists, the ECG waveform is shown as a flat-line
signal accompanied by an ASYSTOLE ALARM message.
If the waveform shown does not appear noisy, but the NOISY SIGNAL message persists,
check all leads for noise before calling a qualified field service engineer.
