The early dynamic of ECG in Takotsubo syndrome presenting with ST-elevation: A comparison with age and gender-matched ST-elevation myocardial infarction

•Presenting ECG in Takotsubo has fewer total abnormal leads, lesser magnitude of ST-elevation/pathological Q waves than MI.•The 4-day evolution of Takotsubo ECG compared to MI is characterised by much more widespread and deeper T wave inversion.•The mean QTc progressively increases in takotsubo whilst in MI decreases.
