title: Premature ventricular beats in a previously healthy child.
abstract: A 12-year-old girl presented to the emergency department with a chief complaint of left-sided chest pain. On physical examination she was noted to have an irregular pulse, and an electrocardiogram revealed 30 to 50 premature ventricular contractions per minute with periods of bigeminy. The patient was admitted to the intensive care unit and treated with antiarrhythmic medication without resolution of her premature ventricular contractions. A diagnostic workup, including echocardiogram, Holter monitoring, and exercise stress testing, was performed. It was determined that the cardiac dysrhythmia, consisting of unifocal premature ventricular contractions with a characteristic configuration on the electrocardiogram, was benign in nature and did not require antiarrhythmic therapy.
