“…index observed in swimmers is compatible with the echocardiographic finding of increased left ventricular mass in this and previous studies [4,5]. However, this finding should be interpreted with caution, because the QRS voltage criteria for left ventricular hypertrophy were derived and tested against the older population and they may not be applicable in young adults or adolescents [22]. In full agreement with previous reports, we did not observe any other electrocardiogrphic differences between swimmers and controls [4].…”

Cardiac adaptation to intensive training in prepubertal swimmers includes vagal predominance, a mild increase in left ventricular dimensions without significant changes in septal or posterior wall thickness, and increased LA size associated with depressed LA systolic function. Evaluation of LA size and systolic function may contribute to a better understanding of the characteristics of the 'athlete's heart' in children and to the differential diagnosis between left ventricular adaptive and pathologic changes.

“…The ECG criteria for LVH shown in Table 1 have evolved over the years. [65][66][67][68][69][70][71][72][73][74][75][76][77][78] Criteria were originally based on R and S amplitudes in standard limb leads I and III, using clinical and autopsy data as reference standards. 4 -6 (Amplitudes of ECG complexes are referred to in millimeters, rather than millivolts.…”

“…These studies give gen eral information on electrocardiographic findings, but are not matched with control groups analyzed using the same criteria. Eight studies in the normal population (pre dominantly air force and living personnel) deal with male subjects, and the sample sizes range from 151 to 67,375 [36][37][38][39][40][41][42], Interobserver variation is considerable [43] mak ing comparison between athletic and control groups from different studies less reliable than those where the same investigators have made comparative studies. Nine compara tive studies in athletic and control groups have been reported with sample sizes rang ing from 10 to 165 [44][45][46][47][48][49][50][51], The majority of the reported studies investigate some com mon electrocardiographic criteria without giving a broad picture of conduction times, depolarization and repolarization, rhythm and conduction disturbances.…”

We have investigated resting electrocardiograms from 1,299 athletic students taken in the same laboratory during the years 1973-1982 and compared them with electrocardiograms recorded in 151 age- and sex-matched sedentary controls. Fifty-two parameters were recorded for each electrocardiogram and computerized. We found that athletic students had a significant lower heart rate, longer PQ time and a prolonged QT_C compared to control subjects. Athletes had higher maximal Q amplitudes in precordial leads, higher R in V₁ and higher indices of right ventricular hypertrophy (RV₁+ SV₅) and left ventricular hypertrophy (Sokolow-Lyon and Grant indices). Furthermore, the athletes had higher maximal ST elevation and higher maximal T wave amplitudes in precordial leads. Sinus bradycardia was more frequent in athletes. All control subjects were in sinus rhythm whereas 0.9% of the athletes had other rhythms (nodal, coronary sinus or wandering pacemaker). Athletes and control subjects did not differ significantly with regard to premature beats, atrioventricular block, bundle branch block or the Wolff-Parkinson-White pattern. We conclude that training induces significant changes in heart rate, conduction times, ST elevation, QRS and T voltage, slow rhythm disturbances and atrioventricular and sinoatrial block were infrequent in the resting electrocardiogram taken in the supine position and disappeared immediately on sitting and during exercise. Training-induced electrocardiographic changes may partly be due to alterations in autonomic tone and partly to structural changes in the myocardium. Different normal criteria for left ventricular hypertrophy may be warranted in athletes.
