Abstract
Background. Several cardiovascular manifestations of coronavirus disease 2019 (COVID-19) have been previously described. QT prolongation has been reported in COVID-19 infection in association with medications such as azithromycin, hydroxychloroquine, and chloroquine but has not previously been reported as a direct result of COVID-19 infection. Case summary. We report the case of a 65-year-old female who developed a prolonged corrected QT interval (QTc) during a hospital admission with COVID-19. This patient was not on any QT prolonging treatment, serum electrolytes were normal, and there was no identifiable reversible cause for the QTc lengthening. Daily serial ECGs during admission showed resolution of the ventricular repolarization abnormality in synchronization with resolution of her COVID-19 viral illness. Discussions. Although there have been reports of QTc prolongation in COVID-19 patients, previous reports of this are for patients receiving medication that causes QT prolongation. This case uniquely demonstrates the development and resolution of this temporary ventricular repolarization abnormality in a patient with a structurally normal heart with no evidence of myocardial fibrosis or edema on cardiac MRI, that is unexplained by other confounding factors, such as medication. This suggests there may be a direct association between COVID-19 and temporary QTc prolongation.
