Resolution of a therapy-resistant focal atrial tachycardia after omega-3 fatty acid supplementation

Abstract

AbstractWe report on a 14-year-old boy with focal atrial tachycardia. After failure of catheter ablation and medical therapy he received 2 g omega-3 fatty acid supplementation while waiting on repeat ablation. Focal atrial tachycardia disappeared 4 weeks later and antiarrhythmic therapy was terminated. We discuss the antiarrhythmic effect of omega 3-fatty acids on the autonomous nervous system based upon six 24-hour Holter electrocardiographs.
