2 Trace automatically (Doppler):
The automatic trace tool always measures the
peak regardless of the Live Trace setting in
Presets setup.
a Display the Doppler spectral trace
(waveform).
b Select Trace on‐screen, and then select
Above or Below for the position of the
automatic trace tool relative to the
baseline.
The automatic trace tool appears in yellow.
The results appear at the bottom of the
screen.
c Freeze the image.
If you want to change the waveform
measured, move each vertical caliper by
pressing and then using the
SELECT
touchpad. Press
If you invert the frozen image or move the
baseline, results are cleared.
If you want to hide the results, select Trace.
d Save the calculation.
To measure a Tissue Doppler Imaging (TDI)
waveform
Ensure that TDI is on. (See "PW Doppler
1
options" on page 32.)
2 On a frozen Doppler spectral trace, press the
key.
CALCS
3 From the calculations menu, select TDI, and
then do the following for each measurement
you want to take:
a From the calculations menu, select the
measurement name.
b Position the calipers. (See "Working with
calipers" on page 47.)
c Save the calculation. (See "To save a
calculation" on page 51.)

LV Mass = 1.05 * {[(5/6) * A1 * (a + d + t)] - [(5/6) * A2
* (a + d)]}
where: A1 = Short axis area, diastole (Epi)
A2 = Short axis area, diastole
(Endo)
a = Long or semi major axis
d = Truncated semi major axis from
the widest short axis diameter to
mitral annulus plane
t = Myocardial thickness

PWT = Posterior Wall Thickness
IVST = Interventricular Septal
