A case of esophagogastroduodenoscopy induced Takotsubo cardiomyopathy with complete heart block

Takotsubo cardiomyopathy (TC) describes a reversible left ventricular dysfunction characterized by apical ballooning and basal hyperkinesis, commonly triggered by emotional or physical distress. TC associated with an esophagogastroduodenoscopy (EGD) has rarely been reported. We report a case of TC with complete heart block (CHB) in a patient receiving an EGD, who had no underlying cardiac disease, had previously tolerated both local and general anesthesia, and who had previously undergone similar endoscopic procedures without complications. The concurrence of both TC and CHB is unique in this case pertaining to a patient with no significant risk factors. The incidence, mechanism and prognosis of TC-associated arrhythmias are also reviewed.
