Troubleshooting Tips
Table 5-4 Troubleshooting Tips for Noninvasive Pacing
OBSERVATION POSSIBLE CAUSE CORRECTIVE ACTION
Device does not function
when PACER is pressed Power off • Check if power is ON.
Low battery • Replace battery with fully
charged battery.
PACER LED is on, but
CURRENT (mA) will not
increase
Therapy electrodes off • Check for message displayed.
• Inspect therapy cable and
electrode connections.
PACER LED on,
CURRENT (mA) >0, but
pace markers absent (not
pacing)
Pacing rate set below patient's
intrinsic rate • Increase PPM.
Pacer oversensing (ECG artifact,
ECG size too high) • Establish clean ECG;
decrease ECG size.
• Select nondemand pacing.
Monitor screen displays
distortion while pacing ECG electrodes not optimally
placed with respect to pacing
electrodes • Reposition electrodes away
from pacing electrodes.
• Select another lead (I, II,
or III).
Pacing stops spontaneously PACER pressed off • Press PACER and increase the
current.
Internal error detected. Service
message indicates an internal
failure. • Check for service indicator.
• Cycle power and start pacing
again.
• Obtain service by a qualified
service technician.
Therapy electrode off • Check for message. Check
pacing cable and electrode
connections.
CHARGE pressed • Press PACER and increase
current, if pacing desired.
Otherwise, proceed with
defibrillation.
Radio frequency interference • Move radio equipment away
from pacemaker.
