Figure 3

Peak septal and lateral mitral annular systolic velocities (S′; panel a) and isovolumic acceleration of the septal and lateral mitral annulus (panel b). Individual (left-hand side of each panel) and group averaged (right-hand side of each panel) echocardiographic measurements of the indicated data during normothermic (NT) and whole-body heat-stress (WBH) conditions. Increases in the indicated parameters by heat stress are indicative of an increase in cardiac systolic function. Figure from Brothers et al.
