Adjusting and Configuring Waveforms

To Adjust the Size or Amplitude of a Waveform

1. Select or in the waveform adjustment button bar for the trace

you wish to adjust.

2. Press the appropriate button to increase or decrease waveform size.

Each button may be pressed up to six times for EGM waveforms,
and up to 4 times for ECG waveforms.

To Normalize a Waveform

➤ To return the waveform to its default size, press the [Normalize] button.

Selecting a Trace Source

You can change the order in which traces appear in the monitor window.
One method is by changing the “source” of one or more of the traces as
described below. Also, you can use the stylus to “drag” a trace to the
desired location as described on page 2-9.

Note: The EGM 1 and EGM 2 sources reflect the programmed electrogram
sources, which are selectable from the

To display the name of the other source, “tap” the trace name at
the left edge of the screen. It will change to show the source of
the other trace.

Adjusting and Configuring Waveforms

Selecting waveforms for Chart Recorder Printing

At any time during a patient session, you can initiate a continuous, live
recording of the patient’s ECG, EGM, and Marker Channel traces on the
programmer’s chart recorder.

By default, the topmost ECG and the topmost EGM waveforms on the
programmer display are enabled for printing (below).

To Select Waveforms for Chart Recorder Printing

♦

1. Select the print button next to a print-enabled waveform that you do

not want to print.

Printing disabled for

this waveform

Printing enabled for

this waveform

This disables printing for that waveform. All other waveforms are then
available for selection.

2. Select the blank button next to the waveform you want to print.

The blank button will then change to a print button, indicating that the
waveform is enabled for printing.

Arranging the Traces

In addition to ordering the traces by selecting the source as described on
page 2-7, you can use the stylus to “drag” a trace to the desired position.
The procedure below shows how to move the Marker Annotation trace
from its current position to a position over the ECG Lead II trace.

To Move a Trace Using the Stylus

♦

1. Press and hold the stylus against the name of the trace you want
to move.

2. Without lifting the stylus, drag the box now appearing around the
trace name and waveform adjustment button bar to the desired
location.

Note: To change the position of a superimposed trace by dragging it,
the source that you want to move must show at the left edge of
the screen.

3. When you have the box positioned where you want the trace to
appear, lift the stylus. If you are positioning the trace over another,
the trace will “snap” into position.

To equalize the spacing between the traces in the new arrangement,
select the
