Filter
The ECG plot-frequency filter (or print filter) can be set to 40 Hz, 150 Hz, or 300 Hz. The plot-frequency filter does
not filter the acquired digital record. A 40 Hz plot-filter setting will reduce the noise (40 Hz and higher frequencies)
on the printed ECG, and a 150 Hz plot-filter setting will reduce the noise (150 Hz and higher frequencies) on the
printout; a 300 Hz plot-filter setting will not filter the printed ECG. The filter setting is printed at the bottom right
corner of the ECG printout.
WARNING: When the 40 Hz filter is used, the frequency response requirement for diagnostic
ECG equipment cannot be met. The 40 Hz filter significantly reduces high-frequency components of the
ECG and pacemaker spike amplitudes, and is recommended only if high-frequency noise cannot be reduced
by proper procedures.
Paper Speed
Configure to 25 mm/s or 50 mm/s for default ECG printouts.
Rhythm Paper Speed
Configure to 5 mm/s, 10 mm/s, 25 mm/s, or 50 mm/s.
Interpretation Option
The ELI 230 automatically analyzes ECGs and prints the optional interpretation on the ECG printout. This setting
allows you to select or suppress the “interpretive” text on the ECG printout.
NOTE: The ECG interpretation offered by the device are only significant when used in conjunction with a
physician over-read as well as consideration of all other relevant patient data.
Reasons
The reasons statements indicate why a particular interpretive statement was printed. Reasons statements print
enclosed in [square brackets] within the interpretive text if the interpretation option is turned on. Turning the
reasons 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,
and “40+ ms Q WAVE IN V1-V4” is the reason statement or explanation as to why the
interpretive statement was printed.
Append
A status or statement phrase can be appended to the ECG and printed under the interpretive text printout. Either
“unconfirmed report” or “reviewed by” can be selected.
Number of Copies
Defines the number of printed copies when an ECG is taken. A zero (0) setting prints the original only; one (1)
prints the original plus 1 copy; two (2) prints the original plus 2 copies, and so on. Up to 9 copies may be selected.
