Evaluation of Electrocardiographic Changes and Laboratory Parameters in Pediatric COVID-19

Abstract

Objective: Cardiac involvement of Coronavirus 19 disease (COVID-19) may be reflected by electrocardiographic (ECG) changes. ECG changes that may occur in hospital admission for COVID-19 in children have not yet been fully evaluated. Materials-Methods: We examined 83 children admitted to our hospital with proven COVID-19. A detailed clinical examination, 12-lead ECG and laboratory tests were recorded. And then all laboratory parameters were evaluated by age. Results: P wave amplitude was normal in 77.1% and high in 22.9% of study population. There was a significant difference in white blood cell (WBC), lymphocyte, neutrophil, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), D-dimer values between the group with P wave amplitude normal and the high group. 13.3% of patients had first degree AV block and 86.7% did not. There was a significant difference between the groups in WBC, lymphocyte, D-dimer, AST values. In our study, there was right ventricular hypertrophy (RVH) in the ECG of 17 cases. There was a significant difference in WBC, lymphocyte, D-dimer, LDH, AST values between groups with and without RVH. In addition, there were positive correlations among V1R, V6S, V1 R / S ratio and WBC, lymphocyte, D-dimer, creatinine kinase (CK), creatinine kinase isoform MB (CK-MB), LDH, AST values. Conclusions: Pathological ECG findings were associated with laboratory values used in the course of the disease. We think that ECG is a test in the course of COVID-19 in children, which may make important contributions to clinicians to manage the patients when interpreted correctly.
