Autotrace

Overview

Automeasure refers to generic PW measurements performed using Auto-Dop

Trace, and the results are

not associated with a Calculation Package. Autocalc

refers to measurements performed using Auto-Dop Trace that are associated with

a specific Calculation Package, and the results

are entered in the Report.

If the strip is live or in cine play, the measurement will be updated at the end of

each cardiac cycle or time interval.

If the strip is frozen, two BLUE vertical line calipers will delimit the current cardiac

cycle (or cycles if averaging is enabled) and the current measurement for the

interval will be displayed. Moving the Trackball left or right will shift the delimiters

to the previous or next interval and update the measurement or calculation

accordingly.

Pressing the Set button selects either the left or right Auto-Dop delimiters for

individual positioning. This allows the user to fine-tune the cardiac cycle to be

used in the Auto-Dop calculations by as much as 50% of that detected by

Auto-Dop Trace. The first press of the Set button selects the delimiters for

positioning in the order of left > right > both, with subsequent Set button presses

repeating this selection cycling.
