One-hundred and fifty-three elite male athletes without apparent heart disease, symptoms, or arrhythmias were studied. Methods: Fifty-six athletes (37%) had increased left ventricular mass (>134 g/m**2). All athletes underwent time-domain SAECG on 300-400 heart beats recorded at rest from three bipolar orthogonal tests with a filter setting of 40-250 Hz. Criteria for abnormality were 1) filtered QRS duration >114 ms, 2) duration of low-amplitude signals >38 ms, or 3) root mean square voltage of the last 40 ms of the filtered QRS <20 micro-V. Results: The prevalence of abnormal SAECG was 7.2% (abnormality of one parameter), 6.5% (abnormality of two parameters), and 5.8% (abnormality of three parameters). The prevalence of abnormal SAECG was similar in athletes with or without increased left ventricular mass. Conclusions: In conclusion, this study showed 1) the low rate of positive results of SAECG parameters in top-level male athletes, similar to that found in healthy sedentary subjects; and 2) the lack of correlation between left ventricular mass and overall SAECG parameters.
