Background Some of the drugs used for the treatment of coronavirus disease (COVID-19) can increase the risk of corrected QT (QTc) interval prolongation, which may trigger arrhythmia or even death. Due to the low sensitivity of the reverse transcriptase-polymerase chain reaction (RT-PCR) test, chest computed tomography (CT) imaging is being used for COVID-19 diagnostic correlation and to evaluate whether there is pneumonic involvement in the lung. Objective In this study, we aimed to investigate the correlation between lung changes on CT and QTc interval changes on ECG in non-ICU patients with COVID-19 who have a positive PCR test when using drugs that can prolong the QTc interval. Methods This was a single-centre retrospective cohort study of hospitalized non-ICU patients. The study included 344 patients (56.1% men) with a mean age of 46.34 +/- 17.68 years. The patients were divided into four groups according to their chest CT results: those having typical, atypical, indeterminate, or no pneumonic involvement. The mean QTc intervals and heart rates calculated from electrocardiograms (ECG) during admission to the hospital and after the treatment were compared. Results No significant differences were found between the groups' age, gender, and body mass index (BMI). In addition, no significant differences were found between the groups' mean QTc interval values at admission (P:.127) or after the treatment (P:.205). The groups' heart rate values were also similar, with no significant differences in the mean heart rate on admission (P:.648) and post-treatment (P:.229) ECGs. Conclusion This study has demonstrated findings of COVID-19 infection based on chest CT does not correlate with QT interval prolongation in non-ICU COVID-19 patients. There is a need for additional larger studies investigating the effect of chest CT findings on QT interval prolongation and bradycardia in COVID-19 patients.
