3.6 Apply a notch filter
ECG traces can contain noise that is due to AC mains interference. This makes the traces
harder to read. You can filter out noise by applying a notch filter. When you apply a filter, the
original ECG signal is not permanently changed. You only change the way it is displayed on the
monitor. You can always restore the original signal.
To apply a notch filter while you view an ECG:
In
the
ECG
menu, select
Display
and
Settings
. And select a
Notch filter
and
Strength
. The Notch filter can be set on 50Hz (Europe), 60Hz (USA) or Off. If no
extensive AC mains interference exists we recommend setting the Notch filter Off.
In case of interference, first try to eliminate that interference as much as possible. If
eliminating is not possible try using a notch filter set to normal strength or in case of
very strong interference set it to strong or aggressive.
Caution
Extensive filtering may affect the shape of the ECG trace
