Electrocardiography ECG

Zeus IE provides the following functions:
– ECG display
– Heart rate display
– Detection of arrhythmia events
– ST analysis
– Display of ECG data

The HR/PLS parameter box displays:
– Heart rate
– Lead
– ST value

(prerequisite: Display all button has been config-
ured, see page 332):

Determining mean values from the ECG
The monitor detects QRS complexes with ampli-
tudes between 0.2 and 5.0 mV and a QRS width of
70 to 120 ms for adults and 40 to 100 ms for ne-
onates, see notes regarding QRS detection in the
"Fault – Cause – Remedy" chapter. The heart rate
is calculated within a range of 15 to 300 bpm by
means of the RR intervals in the last 10 seconds,
where the two longest and two shortest RR inter-
vals are excluded from the calculation. The aver-
age is created from the remaining intervals and this
result is displayed as the current heart rate in the
HR parameter field of the main screen.

ECG safety instructions
Observe the internal instructions of the hospital!
Remove unprotected electrodes from the pa-
tient before defibrillation.
WARNING
Conductive parts of the electrodes and con-
nections (including the neutral electrode)
must not come into contact with other con-
ductive parts (including grounded parts). Risk
of electric shock.
WARNING
Defibrillation electrodes must never be placed
over ECG electrodes or ECG leads. A dis-
charge could prevent defibrillation and cause
injuries to clinical staff and the patient.
WARNING
Evoked potential equipment can cause faults
in ECG monitoring.
ECG with pacemakers
Special care must be taken with pacemaker pa-
tients in ECG analysis.
While monitoring pacemaker patients, QRS com-
plexes may possibly not be counted correctly. A
threshold alarm for the lower heart rate may occur
by mistake:
– For fusion beats and asynchronous pacemak-
ers with coupling intervals between +10 and
–90 ms.
– For asynchronous pacemakers with overshoot
With certain pacemaker patients, Zeus IE can-
not accurately measure heart rate as well as
frequency-dependent arrhythmia events.
WARNING
Turn on pacemaker detection for pacemaker
patients only. Turn off pacemaker detection for
patients without pacemakers.
