Background:
Takotsubo cardiomyopathy is a non-ischemic cardiomyopathy characterized by acute left ventricular systolic dysfunction with transient wall motion abnormalities without a culprit coronary stenosis or other concurrent diagnoses. Its coexistence with transient high-degree AV block is very infrequent.
Case Presentation:
A 61-year-old man presented with a new onset of high degree AV block without ST segment deviations developing an anterior and apical dyskinesia with a low left ventricular ejection fraction in the absence of coronary artery disease.
Conclusion:
Atrioventricular block is an uncommon presentation of Takotsubo syndrome. The management of patients with relevant conduction disorders in this scenario is a challenge for the clinician. In case of persistence of advanced conduction disorders, it seems appropriate to implant a pacemaker.
