Santoro F, et al. - This study hypothesized an association between dynamic changes of QT corrected (QTc) interval during hospitalization for takotsubo cardiomyopathy (TTC) and outcome at follow-up. Findings suggested a possible association of prolonged QTc intervals at admission with a higher risk of cardiovascular rehospitalization at follow-up. The post-admission dynamic increase of QTc intervals was characterized by a trend toward a better prognosis.
