Arrhythmia monitoring
NOTE: For optimal results, select
STfilt
as the ECG filter. For details, see page 55.
Selecting arrhythmia analysis mode
NOTE: With the L-FICU03 software license only severe analysis is
available.
1. Press the
ECG
key.
2. Select ECG Alarms - Arrh. Alarms - Analys.:
Severe detects asystole, bradycardia, tachycardia, ventricular
fibrillation and ventricular tachycardia.
Extend detects (in addition to the types mentioned above),
ventricular run, ventricular couplet, R on T PVC, ventricular
bigeminy, ventricular trigeminy, multifocal PVCs, frequent PVCs
and missing beats.
Setting arrhythmia alarm priority and snapshot creation
1. Press the
ECG
key.
2. Select ECG Alarms - Arrh. Alarms - Adjust .
3. Select the desired alarm by turning and pushing the ComWheel.
4. Select
Red
,
Yellow
,
White
or
OFF
with the ComWheel. Asystole
and ventricular fibrillation alarms are always Red and V Tachy
alarm cannot be selected OFF .
5. To create a snapshot on the alarm, select YES .
6. Select Exit to confirm the changes and return to menu.
NOTE: Alarm priorities can also be set using the S/5 iCentral if the
iCentral configuration allows it.
Starting relearning manually
When the patient’s ECG pattern changes considerably, the monitor
should start relearning a new ECG pattern.
You can start relearning manually through
ECG
- Relearn - Start.
Selecting leads for the arrhythmia analysis
When measuring 5- or 12-lead ECG, you can affect the selection of
the two ECG leads used for detecting beats and ventricular fibrillation.
The selection of user leads (ECG1, ECG2, ECG3) on the monitor
affects the leads used for detection. The first lead used for detection
is lead I or II. The algorithm uses the lead appearing first in user leads.
The second lead used for detection is one of the precordial leads (V1 -
V6). The algorithm uses the precordial lead appearing first in the user
leads.
To change the user lead:
1. Press the
ECG
key.
2. Select a lead for ECG1 Lead, ECG2 Lead, ECG3 Lead .
3. Start the relearning manually by selecting Relearn - Start .
NOTE: With a 3 leadwire trunk cable, the algorithm uses the only one
available lead
ECG1 Lead , which is I, II or III, depending on the
selected user lead.
