Figure 1 Combined Analysis in a Patient With Significant Dyssynchrony Prior to Resynchronization Therapy
(Top) Tissue Doppler time-velocity curves were derived from 12 sites: basal and mid levels from apical 4-chamber, 2-chamber, and long-axis views. Representative paired curves from 6 sites are shown illustrating a significant opposing wall delay of 110 ms (white arrows). (Bottom) Speckle-tracking time-strain curves of 6 radial sites are shown from the midventricular short-axis view with a significant anterior septum to posterior wall delay of 310 ms (yellow and purple arrows). AVC = aortic valve closing; AVO = aortic valve opening.
