Controlling Arrhythmia Alarms
Touch ALARM YES or NO to enable or disable alarms for couplets, single
abnormals, or tachycardia. Disabling alarms for a specific arrhythmia prevents
alarm generation for subsequent detection of that arrhythmia class. At least one
episode of the class must be stored before the alarm can be disabled.
Clearing a Class or Event
When you clear a class, the system removes it from memory. Touch the ENTIRE
CLASS key to clear the displayed class and template from memory and from the
trend buffer. When the system finishes clearing the class, the Arrhythmia Review
menu appears and displays the next class.
Touch the LAST EVENT key to remove only the most recent occurrence of the
displayed class from memory. The LAST EVENT key is only active for abnormal
and couplet classes.
When you clear the most recent event:
• the system removes the most recent occurrence of that class from memory.
• the system displays the message The last occurrence of this class was
deleted in place of the cleared waveform.
• the system updates the frequency and last occurrence totals. The system
does not redisplay the updated information until you redisplay the class.
Merging Classes/Trends
Merging enables you to take two different classes or trends from the same group
and merge them together into a single class, combining the trend history and time
of last occurrence. When the module is frequently storing a single morphology as
two different classes, merging the classes opens up storage for new classes while
saving all arrhythmia data.
Merging Classes
Two classes may be merged when the system interprets two abnormal beats as
different classes but the clinician sees them as the same class. This could occur if
a patient's dominant beat is experiencing frequent changes in polarity or when the
electrodes have been repositioned.
At the start of merging two classes, one class appears on the left side of the
screen and the second class appears on the right side. The message “Merge
these classes or select another class” appears at the bottom of the screen.
If the two classes look clinically the same, they can be merged by touching the
MERGE CLASSES key. Once merged, the first beat will be displayed as a
template on the left side of the screen with the message (M1) following the class
title. Any subsequent beat that fits any of the merged templates will then be stored
in that class.
