Arrhythmias in Takotsubo Cardiomyopathy

摘要: Acute emotional or physical stress can trigger a catecholamine-mediated myocardial stunning known as takotstubo cardiomyopathy (TCM). Although TCM is generally reversible, it be associated with significant morbidity, including secondarily to cardiac arrhythmia. Lethal arrhythmias such heart block, ventricular tachycardia, and fibrillation have been described. Repolarization abnormalities lead characteristic T-wave QT prolongation that place patients at increased risk for arrhythmia, torsades de pointes. This article focuses on the arrhythmic complications explores underlying etiology of these arrhythmias.
