Spontaneous-Onset Atrial Fibrillation in a Toddler with Review of Mechanisms and Etiologies
Section of Pediatric Cardiology, Penn State Geisinger Health System, The Milton S. Hershey Medical Center, Hershey, Pennsylvania Atrial fibrillation is a relatively rare form of arrhythmia in the pediatric population. When it is seen in an infant or child, it is often associated with a structural heart abnormality, particularly after surgical repair or palliation of congenital heart disease. Other episodes may be associated with metabolic derangements. This report discusses the unique case of a toddler with newonset atrial fibrillation that was devoid of a readily identifiable etiology. It also reviews the literature and the implications of such a case for the primary care practitioner.
