ECG
WARNING
— PACEMAKER INDICATION — Pacemaker activity is indicated
on the electrocardiogram through the display of a different
colored pacemaker marker pulse. All pacemaker marker
pulses appear upright and uniform and should not be used
for diagnostic interpretation.
WARNING
— PATIENT HAZARD — A pacemaker pulse can be counted as
a QRS during Asystole when pacemaker detection is on. Keep
pacemaker patients under close observation.
WARNING
— PATIENT HAZARD — Asystole may not be detected if the
patient has a pacemaker that produces high-amplitude pacer
spikes, the pacemaker detection is on, and a PDM is used.
Keep pacemaker patients under close observation.
Pacemaker detection points to note
●
PDM, TRAM, combination monitoring: Pacemaker detection must be turned on at
the monitor. It must be used whenever the monitored patient has a pacemaker.
●
E-modules: Pacemaker detection is always on.
●
E-modules: If the patient has an atrial pacemaker, ST calculations can be performed
if the pacer spike does not coincide with the ISO point’s adjustment range.
Selecting the pacemaker detection
With E-modules the pacemaker detection is always enabled.
With PDM, TRAM, and combination monitoring it must be turned on. However, you
may disable pacemaker event processing by turning off pacemaker detection. When
pacemaker detection is turned off, the monitoring device ignores pacemaker pulse
detections which may adversely affect the heart rate accuracy of the monitoring
device.
1. Select the HR parameter window.
2. Select the Advanced tab.
3. Select a value from the Pacemaker Detection list.
List options are acquisition module dependent:
●
E-modules:
￭
Show : Displays pacemaker spikes on the ECG waveform.
￭
Hide : Hides the pacemaker spikes on the ECG waveform.
￭
Sensitive : Increases pacemaker detection sensitivity and displays the
pacemaker spikes on the ECG waveform. By selecting this option you can
improve the detection of small amplitude pacemakers. However, this mode is
also more sensitive to false pacemaker detections.
●
PDM:
￭
On : Turns on pacemaker detection.
￭
Off : Turns off pacemaker detection.
●
TRAM, combination monitoring:
￭
Off : Turns off pacemaker detection.
