Schematic of measured study parameters. At the top velocity markers are presented, in the middle – strain markers, at the bottom – strain rate markers. S' = peak systolic velocity, PS' = peak post-systoloc velocity, E' = early diastolic wave, A' = late diastolic wave, SS = peak systolic strain, PSS = peak post-systolic strain, PSI = post-systolic index, SSR = systolic strain rate, PSSR = post-systolic strain rate, AVC = aortic valve closure, MVO = mitral valve opening, MVC = mitral valve closure, AVO = aortic valve opening, IVRT = isovolumic relaxation time, IVCT = isovolumic contraction time.
