Silent Signals: Analyzing Repolarization Heterogeneity and Autonomic Modulation in Children With Euthyroid Hashimoto’s Thyroiditis

Children with eHT exhibit increased myocardial repolarization heterogeneity and reduced HRV, indicating a potential risk for arrhythmias. These findings highlight the necessity of regular cardiac symptom inquiry and ECG controls in the follow-up of these patients, considering both thyroid function and underlying autoimmune processes. Further research is needed to clarify the long-term cardiovascular risks of eHT in children.
