AIMS Negative T waves and QTc prolongation often occur in patients with Takotsubo syndrome. Description of typical electrocardiographic changes could be a diagnosis element of this syndrome. This study aimed to clarify on the one hand the more preciously possible the typical electrocardiographic changes, and on the other hand, the timing of occurrence of these abnormalities compared to the trigger occurrence, the symptoms onset and the hospital admission. METHODS AND RESULTS We studied ECGs at admission of 59 patients with Takotsubo syndrome, a 'reference' ECG and each one available during the first five days after admission.We observed significant changes on the pathological ECG compared to reference ECG: the mean number of leads with negative T waves (7.4 ± 1.9 mm vs 2.1 ± 1.4 mm, p
