5 ALARMS AND MESSAGES
Heart Rate, Arrhythmia, ST Segment Analysis
Message Possible Cause Suggested Action
Message: Arrhythmia
Relearning
Parameter value: LRN
The monitor is learning the
patient’s normal QRS complex to
use as reference.
• Wait until the message
disappears from the screen.
Message: Asystole
Parameter value: ASY
No QRS detection for the last 4
seconds.
Heart rate is below 15 beats/
minute.
• Observe the patient and treat if
clinically indicated.
• Select a lead with at least an
amplitude of 0.5 mV.
• Select another lead to meet the
above criterion.
• Reposition or change the
electrodes if the amplitude is still
low.
• Use good skin preparation.

parameter value:

The monitor has detected a lead-off
condition for the currently
processed lead. The cause could
be one of the following:
Unplugged cable
Broken cable
Loose lead wire
Faulty lead wire
Dried out gel on the electrode
Wrong cable type selection.
The M
ULTIMED/NEOMED pod may
be defective.
• Check the patient cable and lead
wires carefully.
• Check the M
ULTIMED/NEOMED
pod. Replace pod if defective.
• Replace any cable or lead wire
that is suspect.
• Reapply gel on the electrode or
change the electrode (if
disposable).
• Select another ECG lead for
processing if the electrode or lead
cannot be replaced.
* For all the electrode disconnected messages (V, V+ RA, LL, LA, RL) the parameter box shows
*** if this is the lead currently being monitored. If another valid lead is being monitored (i.e. ECG
1&2) then the parameter value for HR, ST<lead1> and ST<lead2> is <value>
Message: ARR
