Our objectives in this study were to determine the incidence of abnormal signal-averaged ECG (SAECG) and its relation to the extent and type of exercise in young healthy athletes, and to evaluate the association, if any, between the development of abnormal SAECGs and vigorous exercise. The presence of an abnormal SAECG was evaluated in 796 athletes (mean age 19 years), and its relation to findings on 12-lead electrocardiogram, echocardiogram, and the presence arrhythmias was studied using Holter monitoring. An SAECG was considered abnormal when any one of the three following criteria was met: filtered QRS duration of more than 114 msec, root-mean-square voltage in the terminal 40 msec of less than 20 μV, or a voltage of less than 40 μV for more than 38 msec. Abnormal SAECGs were present in 68 (8.5%) of the athletes and were associated with a smaller left ventricular mass. Athletes who performed anaerobic exercise tended to exhibit a high incidence of abnormal SAECGs, which was associated with a smaller left ventricular mass. No serious ventricular arrhythmias were observed on 24 h Holter monitoring or during the follow-up period of 20±10 months. There were no sudden cardiac deaths. Continuous anaerobic exercise may induce abnormal SAECGs through the development of delayed myocardial conduction or electrical inhomogeneity in cardiac tissue. The presence of an abnormal SAECG was unrelated to the development of arrhythmias in young athletes.
