Some proposed medications, most notably chloroquine, hydroxychloroquine, and azithromycin, have shown an increased risk of ECG changes in the settings of past diseases, specifically QTc interval prolongations (12) (13) (14) (15) . In this systematic review, we aimed to provide the researchers and clinicians with an update on the diverse patterns observed in the ECG of patients with COVID-19. The other four studies administered both monotherapy (chloroquine/hydroxychloroquine) and combination treatmentfor COVID-19 patients and confirmed that combination therapy is associated with a higher risk of QTc interval prolongation compared with monotherapy (18) (19) (20) (21) . In a similar case series study, Bessiere and colleagues (21) reported a broader difference in the two groups' ECG outcomes, indicating 5% and 33% of patients developing QT prolongation in the monotherapy group and combination therapy, respectively.	./cache/cord-354337-a70avg2x.txt	./txt/cord-354337-a70avg2x.txt
