Product Manual

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

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.
