Figure 2: (a) Grayscale short-axis image of the mid-left ventricle at the level of papillary muscles in a healthy control participant. Division of myocardium into six segments is shown. (b) Software-based strain measurement by tracking of speckles. Amplitude of the strain is color coded. (c) Circumferential strain curves of the six segments traced over the cardiac cycle with the yellow dot placed at the nadir, that is, peak strain. Standard deviation of the six time-to-peak strain curves is below 74 ms, thus showing synchronous contraction. MA: Mid-anterior, MAL: Mid-anterolateral, MIL: Mid-inferolateral, MI: Mid-inferior, MIS: Mid-inferoseptal, MAS: Mid-anteroseptal
