5-30 ECG and Arrhythmia Monitoring
Asystole, Vfib, and HR alarms (when there are enough beats to
compute the HR) are active.
All other alarms are not active.
Single Lead Analysis
If single lead analysis is selected, the arrhythmia system begins alearning
whenever:
ECG monitoring is initiated.
The Relearn key is activated (see Initiating Arrhythmia Relearning
Manually p. 5-31).
The ECG Lead or Lead Label is changed manually, or when Fallback
occurs (see ECG Fallback p. 5-23).
A Leads Off INOP condition (that has been active for >60 seconds) ends.
Multilead Analysis
If multilead analysis is selected, the arrhythmia system begins a learning on
both leads whenever:
ECG monitoring is initiated.
The Relearn key is activated (see Initiating Arrhythmia Relearning
Manually p. 5-31).
There has been a Leads Off INOP condition (that has been active for >60
seconds) for both leads, and the condition ends in either lead.
Multilead Analysis With Changes in One Lead
Since the arrhythmia system uses more than one lead for analysis, if there is
a change in one lead, the system does a relearn only on the affected lead.
This happens whenever:
An ECG lead or label is changed.
A Leads Off INOP condition (that has been active for >60 seconds) ends.
Note— During this learning phase the system will continue monitoring
using the operative lead. Therefore, the delayed arrhythmia wave is not
labeled"L". In addition:
Alarm timeout periods are maintained.
Stored arrhythmia templates are maintained for the operative lead.
All alarms turned on are active.
