Key result
Takotsubo cardiomyopathy case presents with rare life-threatening complete AV block, prolonged QT, and TdP.
Why the study?
Takotsubo cardiomyopathy is usually reversible with a good prognosis but can rarely cause life-threatening arrhythmic complications such as complete heart block and torsades de pointes.
Case Report (n=1)
Highlights a rare but life-threatening arrhythmic complication (complete heart block and torsades de pointes) in Takotsubo cardiomyopathy.
May warrant arrhythmia monitoring in Takotsubo; hypothesis-generating for incidence and predictors in prospective studies.
Takotsubo cardiomyopathy (TCM) is a relatively recently recognised clinical entity. It frequently mimics acute coronary syndrome and is accompanied by reversible left ventricular apical ballooning in the absence of angiographically significant coronary artery stenosis. TCM is a reversible condition, and the prognosis is usually well. However, in rare instances, it can be associated with life-threatening arrhythmic complications. Herein, we report the case of a patient with TCM who developed complete atrioventricular block followed by QT prolongation and torsades de pointes. Furthermore, we undertook a literature review of this rare complication of TCM and discussed the formidable therapeutic challenge encountered in such patients.

Inayat et al. (2017) conducted a case report in Takotsubo cardiomyopathy (n=1). Takotsubo cardiomyopathy was evaluated on Development of complete atrioventricular block, QT prolongation, and torsades de pointes. A patient with Takotsubo cardiomyopathy developed rare, life-threatening arrhythmic complications including complete atrioventricular block, QT prolongation, and torsades de pointes.
