Philips Efficia DFM100 - Heart Rate and Arrhythmia Alarms

Heart Rate and Arrhythmia Alarms 4: ECG Monitoring
59
Heart Rate and Arrhythmia Alarms
The Efficia DFM100 detects HR and arrhythmia alarm conditions by comparing ECG data to a set
of pre-defined criteria. An alarm can be triggered by a rate exceeding a threshold (e.g., HR >
configured limit), an abnormal rhythm (e.g., Ventricular Tachycardia) or an ectopic event (e.g., PVC
> configured limit).
HR/Arrhythmia alarms can be generated for the conditions shown in Tables 7 and 8. Once
generated, they appear as alarm messages in the HR alarm status area above the HR numeric. When
ECG alarms are off an
 message appears above the HR numeric. There are both audio
and visual alerts. For more information on alarms, see “Alarms” on page 36.
NOTE: Alarm notification is configurable. See “Alarm Management” on page 38.
