Arrhythmia
*NOTE: Arrhythmia messages
will be displayed when
ALARM PAUSE, ALL
ALARMS OFF, or
DISCHARGED is displayed,
but there are no alarm tones.
Lethal
NOTES: The message "ARR
OFF" appears in the ECG
parameter window when
arrhythmia is turned OFF.
(This message is not displayed
when the monitor is in
Operating Room mode).
Turning arrhythmia on
automatically starts a
"relearn" procedure.
Arrhythmia Conditions
WARNINGS
VENTRICULAR ARRHYTHMIAS—The arrhythmia analysis
program is intended to detect ventricular arrhythmias. It is
not designed to detect atrial or supraventricular arrhythmias.
Occasionally it may incorrectly identify the presence or absence
of an arrhythmia. Therefore, a physician must analyze the
arrhythmia information in conjunction with other clinical
findings.
SUSPENDED ANALYSIS—Certain conditions suspend
arrhythmia analysis. When suspended, arrhythmia conditions
are not detected and alarms associated with arrhythmias do
not occur. The messages which alert you to the conditions
causing suspended arrhythmia analysis are: ARR OFF,
ARRHY SUSPEND, LEADS FAIL, ALARM PAUSE*, ALL
ALARMS OFF*, and DISCHARGED*.
The EK-Pro algorithm simultaneously uses leads I, II, III, and V for ECG
and arrhythmia analysis. The software package detects lethal arrhythmias.
Lethal arrhythmias are Asystole, VFib/VTac, and V Tach unless in
Neonatal-ICU mode. Then Asystole, VFib/VTac, and Brady are the lethal
arrhythmias. (Refer to this chapter, Arrhythmia Conditions, for arrhythmia
definitions.) To manually turn arrhythmia analysis off and on, follow this
procedure:
1. Select ANALYSIS SETTINGS from the ECG Menu. A popup menu
opens.
2. Select ARRHYTH: from the Analysis Settings menu. A popup opens.

control is pressed and the popup menu closed.
Following is an alphabetical list of the arrhythmia messages which will be
displayed when arrhythmia is on and the condition occurs. A definition of
each arrhythmia condition is included. How the monitor responds to each
condition is determined by the alarm level to which the arrhythmia has
been assigned. Refer to Alarm Control section, Arrhythmia Alarm Level, to
view the alarm level settings for arrhythmias.
