“Normal” values are age and disease state-dependent, but for perspective, the case-matched controls with no arrhythmias in our atrial fibrillation study had mean DROMS 310 Carr units, Eh CySH −77 mV, Eh GSH −154 mV, IL-1β 0.4 pg/mL, IL-6 3.9 pg/mL, TNFα 5.5 pg/mL, and hsCRP 3.6 μg/mL. This evidence concerns the gene IL6 and atrial fibrillation.
