ASYSTOLE Ventricular asystole occurs when a QRS has failed to be
detected for 6 seconds
beats per minute.
BRADY Bradycardia is the average of the most recent eight R-to-R
intervals at a heart rate less than the set
limit
.
NOTE: The Brady limit matches the low heart rate limit. If
the low heart rate limit is changed, the Brady limit changes.
VFIB/VTAC Ventricular fibrillation occurs when the instantaneous heart
rate indicates a chaotic ventricular rhythm.
WARNING
VFIB/VTAC should not be considered a substitute for the V
TACH arrhythmia call. Efforts to lower the alarm level of V
TACH can result in missed ventricular tachycardia alarms.
V TACH Adult—Ventricular tachycardia occurs when a run of six or
more ventricular beats is detected with an average heart
rate greater than or equal to 100 beats per minute.
0-2 years—Occurs when a run of six or more ventricular
beats is detected with an average heart rate greater than or
equal to 160 beats per minute.
3-10 years—Occurs when a run of six or more ventricular
beats is detected with an average heart rate greater than or
equal to 140 beats per minute.
11-13 years—Occurs when a run of six or more ventricular
beats is detected with an average heart rate greater than or
equal to 130 beats per minute.
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 detection on will automatically start a
"relearn" procedure.
WARNING
Arrhythmia processing is suspended during external pacing.
Closely monitor alternate parameters, especially Heart Rate in
patients being externally paced. "ARR OFF" is displayed in the
ECG parameter box during all external pacing applications.
Arrhythmia processing
external pacing is discontinued.
