ELI 150
3-10
The ELI 150 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your
country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that the
proper AC filter is selected.
Paper Speed
The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm printouts and
display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for display or rhythm
printing. Paper speed is printed at the bottom-right corner of the ECG printout.
Filter
The ECG plot frequency filter (or print filter) can be set to 40Hz, 150Hz, or 300Hz. The plot frequency filter does
not filter the acquired digital record. A 40Hz plot filter setting will reduce the noise (40Hz and higher frequencies)
on the printed ECG, a 150Hz plot filter setting will reduce the noise (150Hz and higher frequencies) on the printout
and a 300Hz plot filter setting will not filter the printed ECG. The filter setting is printed at the bottom right corner
of the ECG printout.
Height/Weight Units
This option defines the units of weight and height to either pounds/inches (lb/in) or kilograms/centimeters (kg/cm).
Date Format
This option defines the format for entering and displaying the patient’s date of birth in either the U.S. format or the
European format.
For example: July 16
th
, 2003 is displayed as follows:
US Date Format: MM/DD/YYYY (07/16/2003)
European Date Format: DD.MM.YYYY (16.07.2003)
NOTE: the date format option does not modify the acquisition date printed on each ECG. Using the
example above, the acquisition date would print as 16-Jul-2003.
Interpretation Option
The ELI 150 automatically analyzes ECGs and prints the optional interpretation on the ECG printout. This option
allows you to select or suppress the “interpretive” text on the ECG report.
NOTE: A qualified physician should review the computer generated ECG interpretation before the
treatment of any patient.
Reasons
The reason statements indicate why a particular interpretive statement was printed. Reason statements print in
[square brackets] within the interpretive text (if the interpretation is turned on). Turning the reason statement
function on or off does not affect the measurements performed or the interpretive statements selected by the analysis
program.
For Example:
Anteroseptal Infarct [40+ MS Q WAVE IN V1-V4]
Where “Anteroseptal Infarct” is the interpretive statement.
