ST analysis

The AFIB algorithm feature identifies atrial fibrillation arrhythmias for the
transmitter. When an AFIB event is detected, the ATRIAL FIB alarm text is
displayed at the CIC Pro center.
AFIB event patient data is stored for review in the Graphic Trends and Vital Signs
tab sheets.
A patient status alarm is triggered when an AFIB arrhythmia is detected. The message
ATRIAL FIB is displayed in the message area of the display.
NOTE
There is approximately a 90 second delay while the AFIB algorithm verifies the
AFIB arrhythmia condition.
The AFIB alarm defaults to a Message alarm level but can be changed under
Arrhythmia Alarm Level, in the Telemetry Alarm Control Defaults tab sheet on the
CIC Pro center. How the monitor responds to each condition is determined by the
alarm level to which the AFIB arrhythmia detection has been assigned. When set for
Advisory or greater, AFIB alarms will be recorded and displayed in the alarm area on
the CIC Pro center.
NOTE
AFIB alarms can only be adjusted at the CIC Pro center. If AFIB is not available/
enabled at a bedside monitor in Combo mode, you will not be able to
immediately adjust the alarm. You must discharge the patient from the bedside
monitor, adjust the alarm setting at the CIC Pro center and then admit the patient
at the bedside monitor.
The patient's most dominant, normal beat is used for ST measurement. This beat is
identified by the arrhythmia analysis program. Turn ST ON to display the numerics
calculated for ST at the CIC Pro center.
GE identifies the ST segment of the QRS complex as beginning at the J point and
ending 60 milliseconds following the J point in Adult mode. The ST measurement
factory defaults are:
Adult— J+ 60ms
0–2 years— J+ 30ms
3–10 years— J+ 40ms
11–13 years— J+ 50ms
The ST numeric displayed (millimeters) indicates either a positive or negative
elevation in relation to the isoelectric reference point (which is also determined by the
arrhythmia program and the patient's age).
When ST is on, numerics are displayed under each ECG lead label on the screen. (A
negative deflection is preceded by a minus sign.) These numerics are updated about
every 15 seconds.
