[An atypical case of tako-tsubo syndrome presenting with symptomatic bradycardia].

Le résumé fourni par la source

The tako-tsubo syndrome (transient left ventricular apical ballooning with normal coronary arteries), initially described in Japanese patients, is now being increasingly observed worldwide and should be considered in the differential diagnosis of acute coronary syndromes. Angina-like chest pain, electrocardiographic changes and an increase in myocardial markers are often present, as well as history of acute stressful events preceding symptom onset. We report the case of an Asiatic woman in whom typical, reversible abnormalities in left ventricular motion were associated with symptomatic junctional bradycardia. Nevertheless, the patient was completely free from angina and excluded acute pain or emotions in the previous weeks. Coronary angiography showed absence of significant disease and left ventricular function was found to be unremarkable 1 month after the acute event. Although infrequent, atypical presentations of tako-tsubo syndrome have occasionally been reported and, in our opinion, they could provide interesting insights into the ill-defined pathophysiology of the disease.
