Conclusions— Postsystolic shortening is a relatively nonspecific feature of ischemic myocardium and may occur in dyskinetic segments by an entirely passive mechanism. However, in segments with systolic hypokinesis or akinesis, postsystolic shortening is a marker of actively contracting myocardium. SDE was able to quantify postsystolic shortening and might represent a clinical method for identifying actively contracting and hence viable myocardium.
2) vs. FGR 5. 3 (1)) and diastolic dysfunction (isovolumic relaxation time: controls 44 ms (6) vs. FGR 52 (9)). Peak strain and strain-rate values of the left ventricle were not significantly different; however, a postsystolic shortening.
