The cardiac preparticipation sports evaluation.

Purpose Of Review: Sudden cardiac death (SCD) is the leading cause of death in young athletes during sports participation. Preparticipation cardiovascular screening aims to identify those at an increased risk of SCD. This review aims to provide a background of SCD in young athletes, to discuss the various screening recommendations of major medical societies, and to review recent evidence and current practice.

Defining the electrocardiogram in the neonate with hypoplastic left heart syndrome.

Hypoplastic left heart syndrome (HLHS) is a severe form of congenital heart disease characterized by underdevelopment of the left heart. There has been no previously defined "classic" ECG pattern in a large homogenous population of patients with HLHS. We performed a retrospective review of ECGs from neonates with HLHS from 2001 to 2011 with electrocardiograms available prior to surgical intervention.
