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 (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.

SARS-CoV 2 Enfeksiyonlu Hastalarda Kısa Dönem Mortaliteyi Tahmin Etmede Frontal QRS-T Açısı: Bir Analitik Çalışma

Year 2023, , 167 - 173, 31.08.2023
https://doi.org/10.29058/mjwbs.1341878

Abstract

Amaç: Çalışmada frontal QRS-T açısının mortalite ile ilişkisi ve mortaliteyi tahmin etme yeteneği
araştırıldı.
Gereç ve Yöntemler: Bu retrospektif çalışma, bir eğitim hastanesinde 01/01/2021 ile 07/01/2021
tarihleri arasında acil servise başvuran SARS-CoV 2 enfekte hastaları ile yapılmıştır. Hastalar hayatta measkalan
olarak gruplandırıldı ve 30 günlük tüm nedenlere bağlı ölüm verilerine göre öldü. Gruplar, komorbiditeler, demografik özellikler,
laboratuvar parametreleri ve EKG bulguları temelinde eşleştirildi. Frontal QRS-T açısının kısa dönem mortaliteyi tahmin etme yeteneğinin
değerlendirilmesinde alıcı işletim karakteristik incelemesi kullanıldı.
Bulgular: Frontal QRS-T açısı ölen grupta yaşayanlara göre daha büyüktü (53 (25,5-115,5) ve 28 (13-52) p< 0,001). Alıcı işletim karakteristik
analizine göre frontal QRS- için kesme değeri ve eğri altında kalan alan sırasıyla 41,5 (duyarlılık: %62,2, özgüllük: %64,7) ve 0,659 (%95
güven aralığı: 0,606-0,713) olarak belirlendi. Otuz günlük mortalite için frontal QRS-T açısı (≥41,5) olasılık oranı 3,03 olarak belirlendi (%95
güven aralığı: 2,08-4,42).
Sonuç: Frontal QRS-T açısı, acil serviste SARS-CoV 2 enfeksiyonu olan hastalarda kısa dönem mortalite için yüksek özgüllüğe sahip bir
belirleyicidir.
