Arrhythmia Alarms (optional) ECG Monitoring
4.7.1.3 Ventricular Tachycardia (V-TACH) Alarm
A V-TACH alarm is activated as follows:
The range of the V-TACH rate is between 100 to 180 beats per minute.
AND
The V-TACH lethal arrhythmia alarm is activated when the configured number of
consecutive PVCs is reached. The range for the V-TACH threshold is 3 – 15 beats per
minute.
A V-TACH alarm is a Priority 1 alarm event that produces:
Alarm Priority 1 visual and audio alarm indicators.
A V-TACH text message above the ECG1 waveform area.
4.7.2 Non-Lethal Arrhythmia Alarms
A Non-Lethal Arrhythmia is an arrhythmia that is most likely not life threatening to a patient.
Bigeminy, Bradycardia, Couplet, Irregular Heart Rate, PVC/min, Run, Trigeminy, and
Ventricular Rhythm (V-Rhythm) alarms are classified as non-lethal arrhythmia alarms. All other
Non-Lethal Arrhythmias default to Alarm Priority 2. The Alarm Priority for non-lethal
Arrhythmia is user-selectable between 1 and 2.
NOTE: Non-lethal arrhythmia alarms are not latched alarms and
can be acknowledged at any time. To acknowledge a nonlethal
arrhythmia alarm, press the “Silence” key on the
keypad.
4.7.2.1 Bigeminy Alarm
The Bigeminy alarm is activated when three or more cycles of one PVC coupled to one
normal beat are detected.
The Bigeminy alarm is an alarm event that produces:
Alarm visual and audio alarm indicators.
A BIGEMINY text message above the ECG1 waveform area.
4.7.2.2 Brady (Bradycardia) Alarm
The Brady alarm is activated when the heart rate falls to a value 10% lower than the user
selected value for low heart rate alarm.
The Brady alarm is an alarm event that produces:
4.7.2.3 Couplet Alarm
Alarm visual alarm indicator. Since Bradycardia is always accompanied by a low
heart rate alarm, the Priority 1 audio alarm will sound.
A Brady text message above the ECG1 waveform area.
The Couplet alarm is activated when two consecutive PVCs are detected between normal
beats.
The Couplet alarm is an alarm event that produces:
Alarm visual and audio alarm indicators.
A COUPLET text message above the ECG1 waveform area.
