No muscle response to
pacing
Patient’s heart rate may be
greater than noninvasive pacer
ppm
• No action needed.
The Test Load is connected to
therapy cable
• Remove the Test Load and
connect therapy electrodes to
cable.
Patient muscle response is
variable and depends on patient
condition. Muscular response to
pacing is not a reliable indicator
of current delivered.
• No action needed.
Capture does not occur with
pacing stimulus
Current (mA) set too low • Increase pacing current.
(Administer sedation or
analgesia as needed.)
CONNECT CABLE or PACING
STOPPED
message appears
Therapy cable damaged • Replace therapy cable and
perform daily checks per
Operator’s Checklist.
CONNECT ELECTRODES
message appears
Pacing cable or electrode
disconnected
• Reconnect and set current.
Electrodes not adhering to skin • Prepare skin.
Therapy cable damaged • Replace therapy cable and
perform daily checks per
Operator’s Checklist.
Electrodes outdated • Replace electrodes and set
current.
PACING IN PROGRESS message
appears
CPR pressed • Press PACER to stop pacing, if
appropriate, and then press
CPR.
Pacing stops spontaneously
and
PACER FAULT message
appears
Internal error detected • Cycle power and start pacing
again.
• Obtain service by a qualified
service technician.
Intrinsic QRS complexes not
sensed when pacing
ECG size too low • Increase ECG size or select
another lead.
Intrinsic QRS complexes are
occurring during pacemaker's
refractory period
• Adjust PPM.
