[Echocaridographic measurements of left ventricle, heart volume, and maximal oxygen uptake (author's transl)].

Echocardiograms, radiological heart volume and datas by treadmill-exercis of 50 endurance athlets were studied. There was a highly significant correlation between radiological heart volume and left ventricular dimension as well as left ventricular volume including stroke volume. Other good relations were found between echocardiographic measurements and maximal oxygen uptake. These findings of left ventricular echocardiographic dimensions compared with heart volume and oxygen uptake support the value of this method and permit its use in the analysis of physiological and pathologic changes.
