Potentially lethal arrhythmia, occurring at presentation or during hospitalization, are a part of the clinical spectrum of stress cardiomyopathy. There is significant association between the catecholamine provoked nonalternating beat to beat fluctuations in T‐wave morphology, termed T‐wave lability (TWL), and the clinical risk of arrhythmia. We report four patients with diagnosis of stress cardiomyopathy, in whom serial electrocardiography showed macrovoltage nonalternating fluctuations in T‐wave morphology.
