Viewing real-time patient data
BIGEMINY Occurs when three or more bigeminal cycles (a ventricular beat followed by
a non-ventricular beat) are detected.
BRADY Bradycardia is the average of the most recent eight R-to-R intervals at a
heart rate less than the set LOW heart rate limit.
NOTE
The Brady limit matches the low heart rate limit. If the low heart rate
limit is changed, the Brady limit changes.
COUPLET Occurs when two ventricular beats are detected and have non-ventricular
beats before and after the couplet. The coupling interval must be less than
600 milliseconds.
IRREGULAR Occurs when six consecutive normal R-to-R intervals vary by 100
milliseconds or more.
PAUSE Occurs when a 3-second interval without a QRS complex is detected.
NOTE
Some bedside monitors allow the Pause time interval to be adjusted.
For more information, refer to the appropriate bedside monitor’s
operator’s manual.
PVC Isolated premature ventricular complexes occur when a premature
ventricular beat is detected and has non-ventricular beats before and after.
PVC limit When on, the PVC Limit control displays a PVC counter in the ECG
parameter window. When off, the PVC counter is not displayed. Use the
mouse to turn the PVC Limit control
On or Off . The PVC limits are preset in
Alarm Control defaults.
R ON T Occurs when a ventricular complex is detected within the repolarization
period of a non-ventricular beat.
TACHY Tachycardia is four R-to-R intervals at a heart rate greater than the set HIGH
heart rate limit.
NOTE
The Tachy limit matches the high heart rate limit. If the high heart rate
limit is changed, the Tachy limit changes.
TRIGEMINY Occurs when three or more trigeminal cycles (a ventricular beat followed by
two non-ventricular beats) are detected.
V BRADY Adult —Ventricular bradycardia occurs when a run of three or more
ventricular beats is detected with an average heart rate that is less than or
equal to 50 beats per minute.
0-2, 3-10, and 11-13 years —Occurs when a run of three or more ventricular
beats is detected with an average heart rate that is less than or equal to 60
beats per minute.
VFIB/ VTAC Ventricular fibrillation occurs when the ECG waveform indicates a chaotic
ventricular rhythm.
WARNING
VFIB/VTAC should not be considered a substitute for the V TACH
arrhythmia call. Efforts to lower the V TACH alarm level can result in missed
ventricular tachycardia alarms.
