Selecting CLEAR MEMORY clears all arrhythmia and ST segment data and
resets the Abnormals per Minute, Abnormals in a Row, and ST segment alarms.
Upon completion of the learn sequence, ECG alarms are enabled and rate alarms
limits are reset.
Selecting SAVE MEMORY saves all previously-acquired arrhythmia and ST
segment data. Once the learn sequence is completed, ECG alarms are enabled
and rate alarms are reset. The Abnormals per Minute and Abnormals in a Row
alarms remain unchanged. If ST segment level alarms were enabled prior to the
relearn sequence, they will be reset.
Automatic Dominant Class Update
The system uses the following rules to update the dominant class:
• An abnormal class that occurs more frequently than 50% of all beats in the
previous 60-seconds, and occurs three beats more frequently than the
current dominant during that period, automatically becomes the new
dominant class.
• The old dominant is put into an abnormal class and given the status
EXDOMINANT. This class can become dominant again and has the same
characteristics as any other active class.
The message, NEW DOMINANT, is displayed above the ECG trace for
60-seconds after the new dominant is established.
Setting and Adjusting Alarms
In addition to the alarms described in ECG on page 8-3, the Multiview I or II
options provide alarms for these additional conditions.
Abnormals in a Row Alarm
Following the learn sequence, the Abnormals in a Row alarm limit is set based on
either factory defaults or user-defined settings. You can adjust the alarm limit from
two to ten or you can deactivate it.
• Setting the Abnormals in a Row alarm limit to three or greater will initiate a
RUN ALARM message when three or more consecutive abnormal beats (at a
rate greater than 90 BPM) occur.
• Setting the Abnormals in a Row alarm limit to two will initiate a COUPLET
ALARM message when two consecutive abnormal beats occur.
The factory default setting for the Abnormals in a Row limit is five.
Abnormals per Minute Alarm
Following the learn sequence, the Abnormals per Minute alarm limit is set based
on either factory defaults or user-defined settings. You can adjust the alarm limit
from 1 to 99, or it can be deactivated.
To set or adjust alarms for
abnormal beats (arrhythmia
detection must be enabled):
1 Touch ECG.
2 Touch ALARM LIMITS.
3 Touch ALARMS ON.
4 Select ABN IN ROW = or ABN
PER MIN =.
5 Use arrow keys to adjust.
