The presented cases shed light to the fact that the apical dilatation of the left ventricle is only one of the possible presentations of stress induced cardiomyopathy. The main feature of this entity is not the tako-tsubo-like left ventricular dilatation, which is not always present, but the almost universal QT prolongation and negative T waves. These ECG features come a few days after the appearance of the reversible left ventricular dysfunction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
