Figure 4 Changes in LV Dyssynchrony as Assessed With RS, CS, and LS After Cardiac Resynchronization Therapy in Responders and Nonresponders
(A and B) RS; (C and D) circumferential strain (CS); (E, F) longitudinal strain (LS). Solid bars = baseline values, open bars = values at 6-month follow-up. BS-BL delay = difference between time to peak systolic strain of the basal-septal and basal-lateral segments; SDt125 = standard deviation of the time to peak systolic strain of 12 segments; other abbreviations as in Figure 3.
