Checking Paced Status
ECG and Arrhythmia Monitoring 6-9
Checking Paced Status
It is important to set the paced status correctly when you start monitoring
ECG.
Note — Paced status is set at the Information Center and can only be
changed at the Information Center.
When Paced is set to On:
 Pacer Algorithm is switched on. This means that pacemaker pulses are
not counted as extra QRS complexes.
 The pacer spikes are shown in white.
 The paced symbol is displayed.
When Paced is set to Unconfirmed (IIC iX only):
 Pacer Algorithm is switched on. This means that pacemaker pulses are
not counted as extra QRS complexes.
 The pacer spikes are shown in white.
 The paced symbol with ? is displayed.
When Paced is set to Off and your patient has a pacemaker, pace pulses
may be counted as regular QRS complexes, which could prevent an
asystole event from being detected.
Warning
 Pace pulse rejection must be switched on for paced patients by setting
Paced to On. Switching pace pulse rejection off for paced patients may
result in pace pulses being counted as regular QRS complexes, which
could prevent an asystole event from being detected. At
admission/discharge, always check that paced status is correct for the
patient.
 Some pace pulses can be difficult to reject. When this happens, the
pulses are counted as a QRS complex, and could result in an incorrect
HR and failure to detect cardiac arrest or some arrhythmias. Make sure
that pace pulses are detected correctly by checking the pace pulse
markers on the display. Keep pacemaker patients under close
observation.
