Echocardiographic data on 21 top-grade kayak- canoeists and 16 top-grade handball players are compared. While the end-diastolic and end-systolic diameters as well as end-diastolic and end-systolic volumes did not appreciably differ, the posterior wall and particularly the interventricular septum both in diastole and systole were significantly thicker in(More)
We used echocardiography to study anatomic and functional changes of the heart in 25 patients with acromegaly. Asymmetric septal hypertrophy was found in 10 patients, in the range of 12 to 30 mm, with an average of 16 mm. The degree of septum-thickness was severe in 1 case, marked in 5 cases and mild in 4 cases. Concentric left ventricular hypertrophy was(More)
The echocardiographic parameters were followed for 3 years in 15 boys aged 13 years on average, who were beginning competitive canoe race training, and were compared with the corresponding data on 17 boys of the same age who did not take part in sports. As compared to non-sporting boys the 13-year-old canoeist boys had a larger left ventricular(More)
Dipyridamole and dobutamine stress were performed in the same 41 angiographically controlled patients. Both tests were followed by 2 dimensional-echocardiography. The dose of dipyridamole was 0.56 mg/kg/4 min. or 0.84 mg/kg over 10 min., while the dose of dobutamine was 10-20-30-40 and 40 micrograms/kg/min. over 3 min. each step. In addition, to reach the(More)
The authors have examined supposed causes of positive Th-201 stress scintigraphy. Patients were divided into two groups according to the presence of exercise-induced transitory hypoperfusion or in absence of it. In both groups negative coronarograms were verified. Results of two groups were compared according to parameters of the left ventricle function,(More)
