Setting Up Filters

From the Configuration Menu, select Setup ECG Filters. The 12-Lead option has
been factory-configured with the filter settings which remove the most noise from
the ECG. In addition to the default settings, 12-Lead offers a choice of several filter
configurations. These filter settings are detailed below and in Table 2-5.

wander.

without distorting the ECG's ST segment.
• The 0.05 Hz Baseline Wander filter delivers the highest fidelity signal, but pro-
vides the least baseline wander suppression.
• The 40 Hz Noise filter offers maximum noise suppression, but reduces the fidelity
of the signal.
• The 100 Hz Noise filter provides some noise suppression while offering an accu-
rate signal representation.
• The 150 Hz Noise filter delivers the highest fidelity signal, but provides the least
high-frequency noise suppression.
