Abstract

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.

YOĞUN BAKIM COVID-19 HASTALARINDA EKG'DE FRAGMENTE QRS VARLIĞININ YOĞUN BAKIM YATIŞ SÜRESİ VE MORTALİTEYE ETKİSİ

Abstract

AMAÇ: Çalışmamızın amacı hastanemiz yoğun bakım ünitesinde, solunum yetersizliği nedeniyle yatan SARS-COV2 hastalarının elektrokardiyografisinin (EKG) fragmente QRS (f-QRS) varlığı açısından incelenmesi, f-QRS varlığının mortalite, yoğun bakım yatış süresi ve diğer prognostik biyokimyasal tetkikler ile ilişkisini incelemektir.
GEREÇ VE YÖNTEM: Hastanemiz yoğun bakım ünitesinde Haziran 2020 - Ocak 2021 tarihleri arasında yatan 122 ardışık SARS-COV2 hastası çalışmaya dahil edildi. Hastaların EKG’si f-QRS varlığı açısından değerlendirildi. F-QRS varlığına göre hastalar iki gruba ayrıldı. F-QRS varlığı iki deneyimli kardiyolog tarafından teyit edildi. Hastaların biyokimyasal değerlerinden D-dimer, ferritin, CRP, hemogram, troponin değerleri, yoğun bakım yatış süresi, mortalite oranları bu iki grup arasında karşılaştırıldı.
BULGULAR: Yoğun bakım hastalarının %22’sinde f-QRS saptandı. F-QRS grubundaki hastaların CRP, d-Dimer, Troponin değerleri, f-QRS görülmeyen covid grubuna göre anlamlı yüksek idi. F-QRS grubunda mortalite % 38 iken, diğer grupta mortalite % 22 idi (p<0.001). SARS-COV2 hastalarında f-QRS görülme oranı yüksektir.
SONUÇ: SARS-COV2 hastalarında EKG’de f-QRS varlığı kardiyovasküler olayları ve mortaliteyi öngörebilir
