A Rare Case of Second-degree Atrioventricular Block and Takotsubo Syndrome

BACKGROUND: Takotsubo cardiomyopathy is characterized by transient left systolic dysfunction that can mimic acute myocardial infarction. Atrioventricular (AV) block associated with Takotsubo is rare, but a few cases have been reported in recent years. METHODS: We present the case of a 77-year-old woman presenting with second-degree AV and Takotsubo syndrome. RESULTS: The diagnosis of Takotsubo syndrome was based on echocardiogram changes and the absence of coronary artery obstruction on coronary angiography. CONCLUSIONS: We describe a patient with a diagnosis of Takotsubo syndrome and AV conduction defect. These conditions rarely occur simultaneous, but when they do, a dilemma arises regarding pacemaker implantation. LEARNING POINTS: Takotsubo syndrome is a rare disorder that can mimic acute myocardial infarction. Takotsubo syndrome normally resolves by itself, but the associated arrhythmias may need treatment and pacemaker implantation. The timing of pacemaker implantation has to be evaluated on a case-by-case basis.
