B-12 Configuring Your Cardiograph
Filters
Your PageWriter 200/300pi cardiograph has been factory-configured with the
filter settings which remove the most noise from the ECG. In addition to the
default settings, your cardiograph offers a choice of several filter configura-
tions. These filter settings are detailed below and in Table B-3.
l The 0.5 Hz Baseline Wander filter suppresses the greatest amount of
baseline wander. However, in Manual mode, this filter may alter the
ECG’s ST segment.
l The 0.15 Hz Baseline Wander filter provides some baseline wander
suppression without distorting the ECG’s ST segment.
l The 0.05 Hz Baseline Wander filter delivers the highest fidelity sig-
nal, but provides the least baseline wander suppression.
l The 40 Hz Noise filter offers maximum noise suppression, but
reduces the fidelity of the signal.
l The 100 Hz Noise filter provides some noise suppression while offer-
ing an accurate signal representation.
l The 150 Hz Noise filter delivers the highest fidelity signal, but pro-
vides the least high-frequency noise suppression.
l The Artifact filter may be enabled for Auto and Manual ECGs when
the key is pressed. It removes small-amplitude, high-frequency
signals, characteristic of muscle tremor.
