ECG, arrhythmia, and ST segment
1)
Certain ventricular tachycardias have sinusoidal waveforms closely resembling ventricular fibrillation.
Because of the similarities between these waveforms, such types of ventricular tachycardia can be
classified as ventricular fibrillation, the more serious of the two conditions.
2)
N is the event count set in the count column of the arrhythmia setup table (see page 225).
3)
In neonatal mode, you set alarm limits for BRADY in the alarm setup page. The M540 alarms for this
event as a limit violation.
4)
A PVC or another abnormal beat breaks the analysis sequence and restarts analysis.
To select the arrhythmia modes
Select the heart rate parameter field to select
the ECG page directly.
or
1 Select Sensor parameters... from the main
menu bar.
2 Select the ECG tab to access the ECG page.
3 Select the ARR settings tab.
4 Select one of the following modes next to ARR
mode button, located below the arrhythmia
alarm setup table:
– Off
–Basic
– Advanced (only available when the full
arrhythmia option is unlocked)
Arrhythmia display
When arrhythmia monitoring is activated,
arrhythmia events appear in the heart rate
parameter field or in a separate parameter field,
depending on how many leads are selected for
display.
When arrhythmia monitoring is deactivated (see
page 223) and at least one ECG waveform is
displayed, asystole and ventricular fibrillation
events are still reported.
NOTE
To make sure that asystole and ventricular
fibrillation alarms are reported even when HR
monitoring is turned off, set the ASY/VF alarms
selection in the Alarms > General settings page
to Always on (see page 460).
