Continous properly dose trainee process run into adaptive changes of cardiovascular system. One of  accompanying electro physiological change is expansion of QRS complex and presence of RR' waves in the right precordial lead ventholes. It is mostly physiological right bundle branch block with wideness of QRS complex less than 100ms and RR' wave in V1 without any signs of cardiac failure, occured as result of  focal hypertofy liberal wall of right ventricle nearby the border of AV junction and pulmonary conus.
The goal of our research was inspection frequency of electro physiological changes as dilatation QRS complex and presence RR' waves in right precordial leads and presence of trackling auscultatory findings between selected and unselected sportsmen, occured as result of trainee stimulant.
With this research were comprise 77 young sportsmen, 12 to 14 years old,  which were in trainee process longer than 2 years and  adequate group of sportsmen (by age and by branch of sport) with trainee process up to one year. From 77 young sportsmen 49 boys actively train football and 28 boys actively train handball. To all participants in sport camp 12 channel EKG (Cardiax) was done.
KEY WORDS: QRS complex, RR' wave, young sportsmen.
