If the monitor detects ECG leads off during pacing, pacing continues at a fixed rate until the ECG
lead is reattached. During fixed-rate pacing, the pacemaker delivers pulses at the set pace rate
regardless of any intrinsic beats that the patient may have. The monitor continues to display the
pacing rate (ppm) and the current (mA). To reestablish demand pacing, reattach the ECG lead.
While pacing, visually monitor the patient at all times, do not rely on the ECG LEADS OFF warning
to detect changes in pacing function. Routinely assess the ECG for proper sensing, pace pulse
delivery, electrical capture, and mechanical capture.
If pacing electrodes detach during pacing, the CONNECT ELECTRODES and PACING STOPPED
messages appear and an alarm sounds. The pacing rate is maintained and the current resets to
0 mA. Reattaching the pacing electrodes silences the alarm and removes the
CONNECT
ELECTRODES message. The current remains at 0 mA until you increase the current manually.
Troubleshooting Tips for Noninvasive Pacing
Table 4-4 Troubleshooting Tips for Noninvasive Pacing
Observation Possible Cause Corrective Action
1 Device does not function
when PACER is pressed.
Power off. • Check if power is ON .
Low battery. • Connect to AC power.
2 PACER LED on, but
CURRENT (MA) will not
increase.
Therapy electrodes off. • Check for message
displayed.
• Inspect therapy cable and
electrode connections.
3 PACER LED on,
CURRENT (MA) >0, but
pace markers absent (not
pacing).
Pacing rate set below patient's
intrinsic rate. • Increase pacing rate.
Pacer oversensing (ECG
artifact, ECG size too high). • Establish clean ECG;
decrease ECG size.
• Select nondemand pacing.
4 Pacing stops
spontaneously.
PACER button 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 qualified
service personnel.
Therapy electrode off. • Check for message. Check
pacing cable and electrode
connections.
ENERGY SELECT or CHARGE
pressed.
• Press PACER and increase
current.
• Check for service message.
• Cycle power and start pacing
again.
Radio frequency interference. • Move radio equipment away
from pacemaker.
