Electrocardiographic Changes and Arrhythmias in Hospitalized Patients With COVID-19 2020-09-15 .txt text/plain 733 53 37 Subgroup analysis was performed by gender, race, intensive care unit (ICU) admission, troponin-I levels, and SARS-CoV-2 specific therapy (hydroxychloroquine, azithromycin, tocilizumab). Patients had significant lengthening of their QTc intervals during hospitalization regardless of whether they received SARS-CoV-2 specific therapy. Ours is the first report of electrocardiographic changes in patients hospitalized with SARS-CoV-2 showing significant prolongation of PR, QRS, and QTc intervals. PR interval prolonged significantly in all patients admitted with SARS-CoV-2 infection regardless of medication status or troponin elevation. Critically ill patients with SARS-CoV-2 admitted to ICU and those with elevated troponin-I levels had a significantly wider QRS at the time of admission and during the hospital course. Interestingly, we observed significant QTc lengthening during hospitalization in the small subgroup of patients (n=25) not receiving hydroxychloroquine or azithromycin, suggesting an additional unknown mechanism responsible for QTc prolongation in patients with SARS-CoV-2.
