Filter
Baseline Filter
The cutoff can be set for 0.05Hz, 0.12Hz, 0.25Hz or 0.50Hz, for both resting
and Exercise recording.
NOTE: The ‘standard value set is 0.05 Hz. The higher settings should only be
used when absolutely necessary because it could affect the original ECG sig-
nal, especially the ST segment.
Myogram Filter
The Myogram filter suppresses disturbances caused by strong
muscle tremor. The filter is applied by pressing the
Filter
key (or
programmed on as default when the unit is switched on).
The cut off frequency is displayed in the information box -see user guide.
The cutoff frequency is user defined at 25Hz or 35Hz.
Note
: An ECG recorded in auto mode is stored unfiltered. It is therefore
possible to print the stored ECG either with or without passing the myogram
filter.
Mains Filter
The mains filter is an adaptive digital interference filter designed to suppress
ac interference without attenuating or distorting the ECG. Set the mains filter
in accordance with the frequency of your local mains supply.
SBS Filter (baseline)
The baseline stabiliser greatly reduces the baseline fluctuations without
affecting the ECG signal. The purpose of the stabilizer is to keep the ECG
signals on the baseline of the printout. This filter is only effective in auto mode
printout. The Baseline Stabiliser is applied to a recording (on), or not applied to
a recording (off). The cutoff frequency is set above.
SSF Filter (smoothing)
The smoothing filter (SSF: SCHILLER smoothing filter) is a low pass filter to
suppress high frequency artefacts between the QRS complexes. When this
filter is switched on, `SSF` is shown on the bottom line of the automatic
printout.
