Infero-superior kinetics of the aorto-mitral annulus in G+LVH− and G+LVH+ compared with controls. Two-dimensional infero-superior displacement-vs.-time plots in G+LVH−/G+LVH+ vs. matched controls normalized for R–R intervals and baseline positions. Data symbols indicate mean cohort values, and unidirectional whiskers indicate standard errors. Significant P values are highlighted in bold. Abbreviations as in Figures 1 and 2.
