WARNING:
When the 40 Hz filter is used, the frequency response requirement for diagnostic ECG
equipment cannot be met. The 40 Hz filter significantly reduces high-frequency components of the ECG
and pacemaker spike amplitudes, and is recommended only if high-frequency noise cannot be reduced by
proper procedures.
NOTE: A filter setting lower than 150 Hz will reduce the visibility of fast transients in the ECG like
pacemaker spikes or fast notches. For pediatric ECGs a 300 Hz setting is recommended. Filter settings
apply only to displayed and printed data. Data is stored in unfiltered format.
NOTE: The High Pass filter (or base line filter), indicated by the number "0.05" cannot be changed.
RScribe automatically implements a high-performance base line filter that does not distort the ECG
waveform. High Pass filters that do distort the ECG waveform are not available.
AC Filter
To change default ECG AC filter:
Select
AC Filter
Select from: None, 50 Hz, or 60 Hz
NOTE: RScribe removes 60 Hz or 50 Hz interference. The setting you select depends on the line
frequency in your country. For example, use the 60 Hz setting in the U.S. If the setting is correct but you
still see mains interference, check the electrode connections, mains interference sources like transformers
or motors close to the patient, and the connection to the safety ground of the computer. Try operating from
battery power if needed.
