Microvolt T-wave alternans (MTA) is one of markers of electrical myocardial instability. to elucidate normal range of MTA parameters during bicycle exercise test (ET) in adolescent elite athletes. We examined 500 athletes aged 9-18 (mean 16.1+/-2.2) years members of national teams of 27 kinds of sport. There were 333 females with mean age 16.0+/-1.01 years and 167 males with mean age 16.3+/-1.4. All athletes underwent ECG registration in clino- and ortho- positions and bicycle ET with automatic analysis.
