Aim: Current study sought to examine relationship of frontal QRS-T angle with mortality and its ability to predict mortality. Material and Methods: This retrospective study was made in an education hospital with SARS-CoV 2 infected patients admitted to emergency service between 01/01/2021 and 07/01/2021. Patients were grouped as survivor and died according to 30-day all-cause mortality data. Groups were matched in footings of comorbidities, demographics, laboratory parameters and ECG findings. Receiver operating characteristic examination was used for evaluation of the ability of frontal QRS-T angle to predict shortterm mortality. Results: The frontal QRS-T angle was greater in died group compared to the survivors (53 (25.5- 115.5) vs 28 (13-52) p<0.001). According to the receiver operating characteristic analysis, the cut-off and area under the curve were determined as 41.5 (sensitivity: 62.2%, specificity: 64.7%) and 0.659 (95% confidence interval: 0.606-0.713), respectively for frontal QRS-T angle for 30-day mortality. The odds ratio of frontal QRS-T angle (≥41.5) was determined as 3.03 (95% confidence interval: 2.08-4.42). Conclusion: Frontal QRS-T angle is a predictor with high specificity for short-term mortality in the emergency department in with patients SARS-CoV 2 infection.
