Why the study?
Does signal-averaged electrocardiography identify ventricular late potentials in top-level athletes with ventricular arrhythmias, and are these potentials influenced by physiological left ventricular hypertrophy?

Does signal-averaged electrocardiography identify ventricular late potentials in top-level athletes with ventricular arrhythmias, and are these potentials influenced by physiological left ventricular hypertrophy?
Signal-averaged ECG can successfully identify ventricular late potentials in athletes with frequent ventricular arrhythmias, and these findings are independent of physiological left ventricular hypertrophy.
Biffi et al. (1996) studied this question.
