SECTION 4
AC Filter
The device removes 60 Hz or 50 Hz interference. The setting you select depends on the line frequency in your
country. Always use the 60 Hz setting in the U.S. If AC interference is present, check to see that the proper AC
filter is selected.
Paper Speed
Configure to 25 mm/s or 50 mm/s for default ECG printouts. For rhythm printouts and display, speeds of 5 mm/s or
10 mm/s are also available. See Section 3 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 0.05 to 40 Hz, 0.05 to 150 Hz, or 0.05 to 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.
Height Units
Weight Units
Defines the units of height (in/cm) and weight (lb/kg). Settings are selected independently of each other, allowing
for metric or U.S. forms of measurement to be used simultaneously or separately.
Interpretation
The device 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 report.
NOTE: The ECG interpretations 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.
