Alleviation of arrhythmia burden in children with frequent idiopathic premature ventricular contractions by omega-3-fatty acid supplementation

Background Patients at our pediatric outpatient clinic were offered 24-h Holter electrocardiogram (ECG) before and after 3-month period of dietary supplementation with omega-3 fatty acids to monitor the effect on heart rate variability (HRV) and arrhythmias. Methods The study included 17 children (mean age: 11.6 ± 4.9 years) with >1% premature ventricular contractions (PVC) at baseline. 24-h Holter ECG monitoring was performed before and after...
