Item Description

1 Measurement table. Enter or clear the waveform measurement values for the

PR, QRS, QT, R-R, and ST intervals or amplitudes.

NOTE

The QTc value is a calculated value.

2 Measurement window. View, measure time intervals and amplitude for

displayed waveforms, and compare the interval of multiple waveform

complexes.

3 Scroll bars. Move up and down or left and right through the displayed data.

4 Calculated measurement label. Click and drag to reposition.

5 Calipers central handle. Click and drag this handle to position the caliper on a

desired waveform complex.

6 Caliper arm handles. Click and drag these handles to resize or reposition the

caliper arms over the waveform.

Measurement: Choose one of the following leads to measure: I, II, III, V,

AVR, AVL, and AVF. For telemetry only, a second V lead would be available

for display.

Reference: Fill the Enable box with a check mark and choose one of the

following reference leads for display: I, II, III, V, AVR, AVL, and AVF. For

telemetry only, a second V lead would be available for display. Measurements

taken on a reference lead are not recorded in the measurement table.

Gain: Adjust the gain of the displayed waveform.

Marching Calipers: Compare the rate of multiple waveforms.

Grids: Apply a background grid.

Zoom: Zoom in for a closer look at the waveform.

Speed: Change the sweep speed of the displayed waveform.
