This report discusses the more commonly encountered pediatric rhythm disturbances, including sinus node dysfunction, the various forms of supraventricular tachycardia, ventricular tachycardia, long QT syndrome, and the atrioventricular blocks. The electrocardiographic characteristics, electrophysiological mechanisms, clinical presentation, and current acute and chronic management options for each are described.
