Takotsubo cardiomyopathy presenting with QT prolongation and Torsade de pointes in the setting of coronavirus disease 2019

抄録

Cardiovascular complications resulting from coronavirus disease 2019 (COVID-19) are occasionally observed; however, takotsubo cardiomyopathy (TCM) with QT prolongation and Torsade de pointes have rarely been reported. We herein present a case of TCM that occurred after QT prolongation and Torsade de pointes. A 58-year-old woman was admitted because of COVID-19 pneumonia. Seven days after admission, she had a sudden loss of consciousness without any precursor of cardiovascular disease. Monitoring electrocardiogram indicated Torsade de pointes and a prolonged QT interval. Emergency cardiac catheterization revealed the presence of TCM. She received favipiravir and steroids, followed by rehabilitation, which improved her condition. Routine electrocardiography screening is considered for patients with COVID-19 because asymptomatic TCM could be detected.
