We report the case of a post-menopausal female who presented two episodes of transient left ventricular apical ballooning associated with rapid atrial fibrillation within a four-month period. The clinical features of this phenomenon also known as Tako-tsubo mimic acute myocardial infarction and may be a form of catecholamine-induced neurogenic stunning. The case illustrates that typical ECG features could be masked by atrial fibrillation with rapid ventricular response.
