cardiac cycle: Adjust STRAIN START close to the R-Peak.
Adjust
STRAIN END near the T-wave.
• Positive deformation can be mapped by pressing
INVERT.
STRAIN START and STRAIN END must then be adjusted to pick
out the diastolic phase of the cardiac cycle.
• The maximum deformation that is color-coded can be
adjusted using the
STRAIN SCALE assignable. If set too low,
most of the wall will show the color indicating maximum
deformation. If set too high, the maximum deformation color
is never reached.
• Strain 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).
• Low strain values may be masked out with a different color
using the SI Reject control.
