Electrocardiogram changes and wall motion abnormalities in the acute phase of Tako-Tsubo syndrome

Background:The Tako-Tsubo syndrome is still rarely diagnosed in patients presenting with symptoms of acute myocardial ischaemia. It is accompanied by wall motion abnormalities of the left ventricle but significant narrowings or occlusions of epicardial coronary arteries are absent. We investigated a potential relationship between electrocardiogram (ECG) changes, wall motion abnormalities and gender influence of Tako-Tsubo syndrome in an Austrian cohort of Tako-Tsubo syndrome patients.Methods and results:We were recently able to describe four different anatomical types of Tako-Tsubo syndrome in 153 patients of the Austrian Tako-Tsubo syndrome registry. In the present retrospective analysis we investigated ischaemia-related changes in the first diagnostic ECG for the different types of Tako-Tsubo syndrome: the apical and the combined apical-midventricular type showed most frequently a ST elevation (41.1% and 35.3%), whereas the midventricular type of Tako-Tsubo syndrome was more often accompanied by T wave ...
