[7] In a study, evaluating patients with coronary artery disease (CAD), those with FQRS had significantly higher all cause mortality and higher frequency of adverse cardiovascular outcomes (myocardial infarction, sudden cardiac death, revascularization) [8] . The requirement for intensive care unit incresed with increasing levels of troponin in patients with SARS-COV-2 (p<0.000, Table 3 ). Moreover, a significant positive correlation was detected between serum CRP levels,heart rate and frequency of FQRS in patients with SARS-COV-2 (r=0.204, p=0.024, r=0.187 p=0.029) Lineer regression analyses revealed that serum CRP levels and heart rate were the independent predictors of presence of FQRS (Table 4 ).
