[The vectorcardiogram pattern of the athlete's heart (author's transl)].
In order to assess the vectorcardiographic pattern of the athlete's heart, we evaluated the vectorcardiograms of 17 professional footballers; the signs of ventricular hypertrophy were particularly studied. 9 athletes had left ventricular hypertrophy, 3 showed VCgraphic signs of combined ventricular hypertrophy and 5 had normal vectorcardiograms. In all athletes with left ventricular hypertrophy the initial forces had normal spatial orientation (I A left ventricular hypertrophy). Likely, the combined right ventricular hypertrophy explains these VCgraphic patterns. The QRS loop did not show abnormal morphology, only the high magnitude of the spatial maximum QRS vectors was significant for diagnosis of left ventricular hypertrophy. The increase of the cardiac volumes induced by training might explain the high magnitude of the QRS loop.
