Fig. 7.
Bull’s eye plots at end systole for (a) Erc, (b) Erl, and (c) twist angle (in degrees). Data are from 5 normal volunteers. Sectors are gray-scale coded according to the mean values of strains or twist angle, and are marked with mean ± standard deviation. Regional variation was observed for these parameters. Specifically, Erc increased from base to apex, Erl was greater in the postero-lateral wall compared to the antero-septum, and twist angles were higher at the apex compared to the base.
