Flecainide overdose presenting with long QT and acute Takotsubo cardiomyopathy

Takotsubo cardiomyopathy is a rare type of reversible cardiomyopathy characterized by the development of left-ventricular (LV) apical ballooning in the absence of significant coronary arterial disease. Initially described in Japan during the 1990s [1], this diagnosis has become more common with advanced cardiac imaging modalities and increasing awareness. The etiology and pathogenesis of Takotsubo remain unclear, but it often follows extreme emotional or physical stress [1]. Catecholamine-induced myocardial stunning and autonomic dysfunction have becoming leading hypotheses [2].
