  		FIGURE 2.  Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for control subject. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = {sigma}-TES measured for left ventricle and RV, respectively.

  		FIGURE 3.  Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for patient with localized ARVD. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = {sigma}-TES measured for left ventricle and RV, respectively.

  		FIGURE 4.  Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for patient with diffuse ARVD. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = {sigma}-TES measured for left ventricle and RV, respectively.
