Abstract :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 insert ignore into journalissuearticles values(53 insert ignore into journalissuearticles values(25.5- 115.5); vs 28 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(sensitivity: 62.2%, specificity: 64.7%); and 0.659 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(≥41.5); was determined as 3.03 insert ignore into journalissuearticles values(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.
