Visually confirmed post-systolic shortening during the recovery period in four cases of Takotsubo cardiomyopathy.
We report visually confirmed post-systolic shortening (PSS) during the recovery period and the relationship between PSS and electrocardiographic abnormalities in 4 cases of Takotsubo cardiomyopathy (TTC). In these 4 cases, the appearance of visually confirmed PSS during the recovery period coincided with observation of the deepest T wave and the longest QT interval. The transmural repolarization gradient and heterogeneous duration of myocardial contractions may cause PSS in the TTC recovery period.
