System Setup
ECG Acquisition
To configure ECG acquisition, log on to the System Setup screen, select ECG > ECG
Acquisition , and complete the fields described in the following table.
ECG Acquisition
Field Description
Baseline roll filter Removes baseline sway. The higher the settings, the more the filter
smooths out wandering baseline. This filter does not distort the ST
segment displays on the ECG reports.
AC filter Removes AC line artifacts.
Disable auto gain
check. Disables the check for out of range ECG gain. Select No to enable
the auto gain check. If enabled, the system will display a prompt if
the gain of the recorded ECG is either too high or too low, allowing
the user to manually adjust the gain.
Disable lead off
check Disables the check for leads that are disconnected. Select No to
enable the check. If enabled, the system will display a message if it
detects any disconnected leads.
Pacemaker pulse
enhancer Enhances the system detection of small pacemaker pulses. When
enabled, the system is very sensitive and should NOT be placed
close to equipment that emits high frequency radiation. High
frequency radiation can interfere with pacemaker pulse detection
and normal ECG acquisition.
NOTE:
GE Healthcare recommends that this be set to No unless it is
known that the majority of this cardiograph usage will be on
patients with pacemakers. The pacemaker pulse enhancement
can always be enabled on a per-patient basis at the time of ECG
acquisition within the resting ECG programs.
Baseline wander
warning Enables the display a message when the system detects a
wandering baseline.
Muscle tremor
warning Enables the display of a message when the system detects a muscle
tremor.
AC noise level
warning Enables the system to check for powerline interference when
recording ECGs.
Hookup Advisor Enables the Hookup Advisor option, which monitors the quality of
ECG signals for resting, 15-lead, pediatric, vector loops, and Master's
Step measurements. When enabled, the system overrides the
settings for
Baseline wander warning , Muscle tremor warning , and
AC noise level warning .
For more information, refer to “Hookup Advisor” on page 63 .
