Figure 2 Combined Analysis in a Patient With No Significant Dyssynchrony Prior to Resynchronization Therapy
(Top) Tissue Doppler time-velocity curves derived from 12 sites: basal and mid levels from apical 4-chamber, 2-chamber, and long-axis views. The maximum opposing wall delay of only 50 ms was not considered to be significant (white arrows). (Bottom) Speckle-tracking time-strain curves of 6 radial sites are shown from the midventricular short-axis view. The maximum opposing wall delay of only 85 ms was not considered to be significant (yellow and purple arrows). Abbreviations as in Figure 1.
