6 ECG, Arrhythmia, ST and QT Monitoring

Changing the Volume of the QRS Tone

The QRS tone is derived from either the HR or Pulse, depending on which is currently selected as the
alarm source. The QRS volume can be set from 0 to 10 (0 means off).
To change the QRS volume, in the
volume from the pop-up list.

Changing the ECG Filter Settings

The ECG filter setting defines how ECG waves are smoothed. An abbreviation indicating the filter
type is shown underneath the lead label on the monitor display. Filter settings do not affect ST
measurement.
To change the filter setting, in the

large amplitude spikes making the ECG signal look irregular. Low frequency interference
usually leads to a wandering or rough baseline. In the operating room, the Filter reduces
artifacts and interference from electrosurgical units. Under normal measurement conditions,

bandwidth requirements for diagnostic electrocardiographic devices as outlined in the ANSI/
AAMI standard EC11-1991.
When you are using a telemetry transmitter connected via short range radio to the monitor,
the upper bandwidth for all filter settings is limited to 40 Hz.

Choosing EASI or Standard Lead Placement

You must enable either standard lead placement or EASI lead placement.
