[Axis divergence in electrocardiography as a sign of heart disease].

In the ecgs of 3433 patients the QRS- and T-vectors were determined. The borderline between physiological and pathological ranges of axis-divergence is found to show fluctuations. The younger the patient and the steeper the electrical heart axis, the greater is the physiological axis-divergence. Ignoring this fact many young people by mistake are taken to suffer from a cardiac disease on account of a great axis-divergence. On the other hand the same setting often is the only sign of a heart disease. The axis-divergence can be a useful factor for the computer-analyzed ecg, although the evaluation of a tenfold of ecgs seems to be necessary to achieve a statistically significant statement.
