[Electrocardiographic and phonocardiographic findings in Ebstein's anomaly with special regard to its severity (author's transl)].

Electrocardiographically, the combination of the P-dextro-atriale and the RBBB without right ventricular overload almost certainly constitutes a pathognomonic finding in Ebstein's anomaly. The height of the P wave and the duration of the QRS complex are related the the severity of the anomaly. So the higher the P wave, the wider the QRS complex, the more severe is the Ebstein'ngs are detectable in the phonocardiogram. In the mild form, however, a loud systolic click and occasionally a low systolic murmur are present, while in severe forms, there is only a loud systolic murmur, and no systolic click.
