Abstract
Atrioventricular (AV) block is rare in Takotsubo cardiomyopathy (TC). A 66-year-old female presented with fatigue. Her electrocardiogram revealed 3:2 Mobitz Type II AV block, confirmed to be supra-Hisian by electrophysiological study. Echocardiogram and left ventricular angiogram showed moderate left ventricular dysfunction and apical ballooning, whereas coronary angiogram revealed mildly ectatic coronaries. At 2 weeks AV block persisted, needing permanent pacemaker implantation. At 1-month follow-up, she had normal ventricular function and no AV block. Delayed recovery of AV conduction is possible in TC, thus implying to wait for a longer period before implanting a pacemaker.
