start close to the R-Peak. Adjust Tracking end near the
T-wave.
• Negative displacement can be mapped by pressing
INVERT.
TRACKING START and TRACKING END must then be adjusted
to pick out the diastolic phase of the cardiac cycle.
• The maximum displacement that is color-coded can be
adjusted using the
TRACKING SCALE assignable. If set too
low, most of the wall will show the color indicating maximum
displacement. If set too high, the maximum displacement
color is never reached.
• Tissue Tracking provides velocity information only in the
beam direction. The apical view typically provides the best
window since the beams are then approximately aligned to
the longitudinal direction of the myocardium (except near
the apex).
