Inflammatory Markers in Supraventricular Tachycardia: Insights for Emergency Management

Aim: Supraventricular tachycardia (SVT) is a common reason for emergency department visits and can significantly impact patients' quality of life.Certain hematological parameters may support the diagnosis and aid in the clinical management of conditions that often occur in the absence of structural heart disease.This study aimed to evaluate hematological markers, particularly inflammatory parameters, and their potential role in SVT. Materials and Methods:This retrospective study included 243 newly diagnosed SVT patients and 220 healthy controls.Demographic data and laboratory parameters such as white blood cell count, neutrophil count (NE), red cell distribution width (RDW), platelet count, and mean platelet volume (MPV) were analyzed.Additionally, the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio were calculated to assess inflammatory status. Results:The findings revealed that NLR, RDW, and NE levels were significantly higher in the SVT group, while eosinophil, hemoglobin, and hematocrit levels were significantly lower.ROC analysis identified NLR as a significant predictor of SVT, with an optimal cut-off value of 2.62 and a specificity of 72.3%.Although MPV did not reach statistical significance, a proportional increase was observed in SVT, patients. Conclusion:This study highlights the potential role of NLR and RDW as supportive biomarkers in SVT diagnosis.Our findings indicate that NLR and RDW levels were significantly higher in SVT patients compared to controls, suggesting a link between inflammation and SVT pathogenesis.These findings suggest that inflammation may play a role in SVT and that hematological parameters could aid its evaluation.
