12.3.2.3 Changing Pacer Settings
To change pacer related settings, follow this procedure:
1. From the ECG tab, select the Pacer section.
2. Set the desired items.
12.3.2.4 Adjusting the Minimum QRS Detection Threshold
To avoid false asystole alarms when the R wave amplitude is low and missed asystole
alarms during ventricular standstill (tall P waves, but no QRS), a means to manually
adjust the minimum QRS detection threshold is provided.
To adjust the QRS detection threshold, follow this procedure:
1. From the ECG tab, select the Setup section.
2. From the ECG tab, select the QRS Threshold section.
3. Select the arrow buttons to adjust the QRS threshold. Selecting Default resets the
QRS threshold to the default value (0.16 mV).
Options or Buttons Description Default Setting
Paced The option is not configurable at the CMS.
The paced status can be set at the TD60
only. See
"Setting the Paced Status" on
page 7 - 10 for details.
None
Pacer Reject Configures whether or not to reject the
pace pulses.
■
On: the pace pulses are not
counted as extra QRS complexes.
■
Off: the pace pulses are not
rejected.
Off
This option is only available when Paced is set to Yes at the TD60.
CAUTION
•
The setting of QRS threshold can affect the sensitivity of arrhythmia, ST,
QT/QTc detection, and heart rate calculation.
•
If QRS amplitude is low, the monitor might not be able to calculate heart
rate and false asystole may occur.
