Comment on "Prognostic value of T-wave positivity in lead aVR in COVID-19 pneumonia".

Abstract

The study 1 entitled “Prognostic value of T-wave positivity in lead aVR in COVID-19 pneumonia” investigated the relationship between T-wave positivity in lead aVR and the prognosis of patients with COVID-19 pneumonia. The findings suggest that T-wave positivity in lead aVR is a useful predictor of poor prognosis in COVID-19 patients. While the findings of this study are interesting, I would like to point out some potential limitations.
