Purpose
– to analyze the correlation between the RSR’
patern in
right precordial leads (V1-V3) and upper precordial leads (V1-V3
Brugada leads ) on standard ECG and the right ventricular outflow
function ( evaluated by standard echocardiography ) in highly trained
athletes. Material. Gr.I ( control normal ) – 610 c. (280
males;
31±12 years); Gr.II (highly trained athletes: kayak, canoe,
rowing)-110 c.(82 males;23±7 years). Methods 1) standard 12
leads ECG – one/two upper space right precordial leads
(V1-V3,
Brugada ledas). 2) echocardiography – right ventricular
outflow
tract (RVOT) – short axis parasetrnal ( diameters; ejection
fraction; wall thickness); right ventricular inflow tract (RVIT)
– apical 4 chamber (diameters; TAPSE;dP/dt)

Conclusions.
1) The RSR’ pattern was associated with larger RVOT diameter
(27±8, p<0,05) and thicken RVOT free wall
(3,5±0,5,
p<0,01) in highly trained athletes. 2) The RSR’
pattern in
right precordial leads (V1-V3) and upper right precordial leads ( V1-V3
Brugada leads ) on standard ECG was observed in the majority of highly
trained athletes ( Gr. II: 42%/68% ) comparing with normal subjects
(Gr. I: 6%/16% ).
