Figure 2 Example of left ventricular (LV) dyssynchrony assessment in a patient. (A) The color-coded tissue Doppler images four-chamber view. The velocity graphs are presented in the right panel of A. There is extensive LV dyssynchrony with a septal-to-lateral delay in peak systolic velocities of 115 ms (arrows). The accompanying velocity encoded magnetic resonance imaging and velocity graphs are presented in panels B and C, respectively, confirming extensive LV dyssynchrony with a septal-to-lateral delay of 116 ms.
