Abstract

A 75-year-old woman, who had never exhibited a delta wave before, was diagnosed with sigmoid colon cancer and underwent surgical operation. Takotsubo cardiomyopathy (TC) occurred shortly after the operation. About 2 weeks following the onset of TC, a 12‑lead electrocardiogram revealed a delta wave that was present for 50 days, and the patient was diagnosed with transient ventricular pre-excitation. The delta wave disappeared prior to patient's discharge and was never observed thereafter. This transient appearance of a delta wave may be related to a pathological modulation of the autonomic nervous system during the acute phase of TC.

Keywords: Accessory pathway; Delta wave; Pre-excitation; Takotsubo cardiomyopathy.
