To adjust the AFIB arrhythmia patient status alarm level, follow this procedure. When
this option is enabled, the factory default alarm level setting is MESSAGE.
1. Select MORE MENUS > MONITOR SETUP > MONITOR DEFAULTS

2. Locate and select ATRIAL FIB.
3. Select the patient status alarm level.
Performing ST Analysis
Overview
ST analysis begins at the end of the QRS complex and ends with the onset of the T
wave. The point at which the QRS complex meets the ST segment is referred to as the
J point.
The ST numeric that displays in the ECG parameter window indicates the greatest
positive or negative deviation from the isoelectric reference (I) point. Numerics
update every two seconds.
If ST is the second priority parameter (ECG is the first) the ST values display in three
groups:
Anterior (ANT) — V1 to V4.
Inferior (INF) — Lead II, III and AVF.
Lateral (LAT) — Lead I, AVL, V5 and V6.
The default ST display shows three, 30-minute ST trends and three ECG complexes
for leads I, II and V. To change the display default settings, refer to Control Settings
on page 8-9.
ST trends — Displays 30-minute real-time trends for each lead. When in
OPERATING ROOM patient-monitor type, a summation scale also displays.
ST complex — Displays current complex for each lead superimposed over the
reference complex to show ST segment changes. Updates every 16 beats.
NOTE
Trends and complexes are not available from a telemetry transmitter when
performing combination monitoring.
NOTE
The ST algorithm has been tested for accuracy of the ST segment data. The
significance of the ST segment changes needs to be determined by a physician.
