ECG Monitoring Arrhythmia Alarms (optional)
4.7.2.4 Irregular Heart Rate Alarm
The Irregular Heart Rate alarm is activated when the measured variations in the R-R
interval over a period of time exceeds a preset limit established by the arrhythmia algorithm.
The Irregular Heart Rate alarm is an alarm event that produces:
• Alarm visual and audio alarm indicators.
•An IRREGULAR HR text message above the ECG1 waveform area.
4.7.2.5 PVC/minute Alarm
The High PVC alarm is activated when the number of PVCs detected per minute exceeds the
configured threshold. The PVC limit can be set to Off, or 1 to 30 PVCs per minute.
The High PVC alarm is an alarm event that produces :
• Alarm visual and audio alarm indicators.
•A High PVC text message above the ECG1 waveform area.
NOTE: PVC/min will not be displayed during periods of Ventricular
Rhythms, V-TACH, V-FIB and Asystole.
4.7.2.6 Run Alarm
The Run alarm is activated when the number of consecutive PVCs occur at a rate that equals
or exceeds the user defined V-Tach Rate. The number of consecutive PVCs that constitute a
Run is one beat less than the minimum used to identify V-Tach.
The Run alarm is an alarm event that produces:
• Alarm visual and audio alarm indicators.
•A RUN text message above the ECG1 waveform area.
4.7.2.7 Trigeminy Alarm
The Trigeminy alarm is activated when three or more cycles of one PVC coupled to two
normal beats are detected. This rhythm could also cause an Irregular HR alarm.
The Trigeminy alarm is an alarm event that produces:
• Alarm visual and audio alarm indicators.
•A TRIGEMINY text message above the ECG1 waveform area.
4.7.2.8 Ventricular Rhythm (V-Rhythm) Alarm
The V-Rhythm alarm is activated when more than 2 consecutive PVCs occur at a rate that is
less than the user defined V-Tach Rate.
The V-Rhythm alarm is an alarm event that produces:
• Alarm visual and audio alarm indicators.
•A VENTRICULAR RHYTHM text message above the ECG1 waveform area.
