3. Trackball to the same location on the next cardiac cycle and click to place the

next caliper.

4. Continue placing calipers on the cardiac cycles and then right-click on the last

heart beat of the sequence to place your final caliper.

5. If you need to move the entire measurement, click on a measurement line and

then drag and drop it.

M-Mode LV wall trace measurements

Use the LV trace measurement tool to:

 Trace the position of the upper and lower inner walls of the ventricle through

a heart cycle so you can measure the parameters of the left ventricle inner area

 Add a trace of the outer walls to the inner walls that you traced so you can

measure the parameters of the outer walls of the left ventricle

f To trace the inner LV walls

1. Click the LV Area button . The system highlights the button until you

complete your measurement.

2. Adjust the sweep speed to compress or expand the cine loop so you can see

the number of heart cycles you want to measure. Decrease the speed to show

more cycles, increase the speed to show fewer cycles.

3. On the upper wall:

a. Start on either the left or right side of the image window (it doesn't matter

which side you start on) and click to place your first caliper along the

inside of the wall at either the diastolic or systolic peak or valley.

b. Continue to click and place caliper points at the diastolic and systolic

peaks and valleys until you have traced the number of cycles you want the

system to measure.

c. Right-click to complete the trace.

4. On the lower wall:

a. Add caliper points the same way.

b. Right-click to complete the trace.

c. Right-click a second time to complete the measurement and display the

measurements.

5. Work with your trace as required:
