RR Analysis
Option Description
Gain Changes the magnitude of the ECG signal on the display
or in the report. Measurement is in millimeter per millivolt
(mm/mV) and includes the following options:
• 2.5 mm/mV
• 5 mm/mV
• 10 mm/mV
• 20 mm/mV
• 40 mm/mV
• Automatic
The larger the selected measurement, the larger the
waveform appears. Only the appearance 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.
Low Pass Filter Eliminates noise in the waveform by restricting which
frequencies are included. Frequencies are measured in
Hertz (Hz) and include the following options:
• 20 Hz
• 40 Hz
• 100 Hz
• 150 Hz
Selecting a frequency eliminates signals that exceed that
frequency. The smaller the frequency selected, the more
signal is filtered out. For example, a filter of 40 Hz displays
only signals at 40 Hz or less; signals greater than 40 Hz
will be ignored.
CAUTION:
INACCURATE READINGS — Using the filter can result
in a cleaner waveform, but selecting a frequency that
is too low could alter the waveform's morphology,
resulting in an inaccurate reading.
To avoid this, use the filter only to eliminate excessive
noise and use the highest frequency that provides a
readable waveform.
Pace Enhance Improves the readability of pacemaker ECGs. Options are
On and Off .
