Right ventricular dimensions and signal averaged ECG in endurance athletes

What is it about?

This paper examines late potentials in athletes engaged in endurance sports. Late potentials can be a sign of heart muscle disease and a predisposition to serious arrhythmias. The paper shows that most endurance athletes have at least one marker of late potentials possibly based on the normal electrical adaptations to athletic training rather than a serious cardiac fault.

Why is it important?

This paper is important because it shows that the signal averaged ECG will highlight at least one abnormality in most endurance athletes and therefore should be considered relatively non specific.
