End-systolic excursion assessment may miss early dyskinetic motion in ischemia; leaves open whether temporal analysis improves detection.
Simple measurement of endocardial excursion from end-diastole to end-systole may fail to detect important wall motion abnormalities in acute myocardial ischemia due to temporal heterogeneity.
Weyman et al. (1984) studied this question.
