Strong associations with arrhythmia were observed for IL-6 (median 3.90 vs 1.89 pg/mL, p<0.00001) and CRP concentration (6.32 vs 1.47 mg/L, p=0.00009), while MS was associated most strongly with IL-6.
Our present study was performed to investigate whether serum IL-6, -174G>C IL-6 polymorphism and C-reactive protein (CRP) are associated with arrhythmias of unknown origin in children.
