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.
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.
WORDS: QRS complex, RR' wave, young sportsmen.
