Figure 4From: Left ventricular strain and peak systolic velocity: responses to controlled changes in load and contractility, explored in a porcine model Systolic Strain. Systolic strain increased during load reduction in half the group, and notably for the negative inotropy groups. Data are presented as mean ± SEM, n = 13. Filled diamond = Radial projection; Open square = Longitudinal projection. # p < 0.05 with Repeated Measures ANOVA.Back to article page
