Relation of Race to Electrocardiographic Patterns in Elite American Football Players

The purpose of this study was to establish an electrocardiographic (ECG) profile in a biracial population of highly-trained American football players.Intense physical training can induce cardiac structural and functional changes ("athlete's heart"), including 12-lead ECG alterations. That race might play a role in determining ECG patterns has been suggested, although not studied in a large athletic population comparing black and white...
