OBJECTIVE: The aim of our study is to examine the electrocardiography (ECG) of SARS-COV2 patients with respiratory failure hospitalized in the intensive care unit of our hospital for the presence of fragmented QRS (f-QRS), and to examine the relationship between the presence of fragmented QRS and mortality, length of stay in the intensive care unit, and other prognostic biochemical tests. MATERIAL AND METHODS: 122 consecutive SARS-COV2 patients hospitalized in the intensive care unit of our hospital between June 2020 and January 2021 were included in the study. The ECGs of the patients were evaluated for the presence of fragmented QRS. Patients were divided into two groups according to the presence of fragmented QRS. The presence of fragmented QRS was confirmed by two experienced cardiologists. The patients' biochemical values such as D-dimer, ferritin, CRP, hemogram, troponin values, intensive care unit length of stay at intensive care unit and mortality rates were compared between these two groups. RESULTS: f-QRS was detected in 22% of intensive care patients. The CRP, d-Dimer, Troponin values of the patients in the f-QRS group were significantly higher than the covid group without f-QRS. While mortality was 38% in the F-QRS group, it was 22% in the other group (p<0.001). The incidence of f-QRS is high in SARS-COV2 patients. CONCLUSIONS: Presence of f-QRS in ECG may predict cardiovascular events and mortality in SARS-COV2 patients.
