Patient Monitor User Manual Monitoring ECG

NOTE:
1 If 3 Leads is selected in the ECG Setup menu, only Normal can be selected for
Display in the sub-menu.
2 In 12 Leads display interface, the filter can only be set to Diagnosis.
8.6.5 Setting Pace Status
It is important to set the paced status correctly when you start monitoring ECG. To change the
paced status in the ECG Setup menu, select Pace to toggle between On or Off. When Pace is set
to On:
- Pace Pulse Rejection is switched on. This means that pacemaker pulses are not counted as
extra QRS complexes.
- Paced symbol is displayed as
|
on the main screen. At this time, the artifact is displayed on the
screen instead of the actual pacemaker crest. All pacemaker crests are the same, so do not give a
diagnostic explanation about the size and shape of the pacemaker crest.
NOTE:
When monitoring a patient with a pacemaker, set Pace to On. If monitoring a patient
without a pacemaker, set Pace to Off.
WARNING
1 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. Be sure to check the paced symbol on the
display screen has correctly detected the pacing pulse. Keep pacemaker patients
under close observation.
2 For patients with pacemakers, the pace must be switched ON. Otherwise, the pacing
impulse may be counted as regular QRS complexes, which could prevent an asystole
event from being detected. When changing settings and admitting patients, please
make sure the pace mode is always correct.
3 External pacing electrodes: When using pacemakers with external pacing electrodes
on the patient, the quality of arrhythmia is severely degraded due to the high energy
level in the pacemaker pulse. This can cause arrhythmia algorithms can not detect
the pacemaker without capturing or asystole.
8.6.6 ECG Calibration
This item is used to calibrate ECG waveform. When you select this item from ECG Setup menu
again, the ECG waveform calibration ends.
NOTE:
The patients can’t be monitored during ECG calibration.
