Recording a Resting ECG
ECG Options
This system provides several options for configuring an ECG. The options, presented as
option keys across the bottom of the display, are listed in the following tables.
ECG Options–First Row
Option
Description
Patient Data
Opens the patient data entry window.
25 mm/s
Changes the speed of the waveform on the display and printout.
Changing the speed also changes the speed at which the wiper
bar moves across the display.
Measurement is in millimeters per second (mm/s) and includes the
following options:
• 25 mm/s
NOTE:
The initial
measurement
displayed is
set in System

Setup.
• 50 mm/s
• 12.5 mm/s - 5 mm/s
• 12.5 mm/s
When the option includes two speeds (12.5 mm/s - 5 mm/s), the
first speed is for the display and the second speed is for the
printout.
Changing the measurement here does not change the
measurement set in System Configuration.
10 mm/mV.

The initial
measurement

> Resting ECG
Setup.
Changes the magnitude of the ECG signal on the display or in the
report. Measurement is in millimeters per millivolt (mm/mV) and
includes the following options:
• 5 mm/mV
• 10 mm/mV
• 20 mm/mV
• 40 mm/mV
• 2.5 mm/mV
• Automatic
The larger the selected measurement, the larger the waveform.
Only the representation of the waveform changes; signal strength
is not affected.
NOTE:
If Automatic is selected, the system calculates the best gain
based on the peak-to-peak amplitudes of all displayed leads
and the selected display format.
Changing the measurement here does not change the
measurement set in System Configuration.
