Takotsubo syndrome or stress cardiomyopathy is a myocardial functional disorder, which is often associated with situations of physical or emotional stress. It accounts for between 1% and 2% of all those admitted to the Emergency Department due to acute coronary syndrome, and has a prevalence and mortality rate of 4.1% and 2% to 8%, respectively. Up to 10% of the patients have some type of complication.

Epidemiological data are scarce in Colombia. The underlying pathophysiology is still not exactly known, and there is no consensus on the treatment of the syndrome and the associated complications. Therefore, these questions are possible research topics. A clinical case of unusual characteristics is presented, which included rare electrocardiographic, kinetic, and myocardial conduction characteristics. It also had an unexpected clinical outcome, which culminated in cardiorespiratory arrest secondary to a polymorphic ventricular tachycardia due to persistence of the prolonged QT interval. Based on clinical experience and on the available scientific evidence, it is recommended to closely monitor patients with an acquired change in myocardial repolarisation until it returns to normal, and to consider an implantable cardioverter defibrillator in cases of high risk.
