Figure 1 Speckle Tracking Radial Strain Analysis
(A) Short-axis of the left ventricle (LV) at the level of the papillary muscles, with reconstruction of the 6 LV segments. (B) Demonstrates the separate strain-time curves for each individual segment. In this patient example, severe baseline LV dyssynchrony was present; a maximum delay of 220 ms was calculated between the septum (red) and the posterior wall (purple). Site of latest activation was the posterior LV segment (purple) AVC = aortic valve closure.
