Optimizing TSI
• Use apical view when imaging and ensure that both LV
walls and opposing walls are in the view.
• Activate TSI from an optimized TVI display.
• Low time to peak values may be masked out with a different
color using the TSI Cutoff control.
• Optimize 2D gain for clean chamber
• ATO can be used
• Clean ECG trace
• Acquire one or more complete heart cycles
• Default TSI start and end times are suggested
• When analyzing TEE images where systolic velocities are
negative, the detection mode may be changed to "Time to
peak negative velocity" using the Invert control.
