[Pre-excitation ventricular syndrome. Syndrome of the additional latent retrograde-conducting ventriculoatrial connection].

A new syndrome of ventricular pre-excitation syndrome is differentiated--of additional obscure retrograde conducting ventricular-atrial connection, different from the so far known syndrome of Wolff-Parkinson-White, Lown-Ganong-Levine and syndrome of Mahaim. That is determined by the anatomically confirmed additional connection, conducting only retrogradely from ventricles to auricle. Diagnostic criteria have been developed from the most significant clinical symptoms and electrocardiographic constellations. With the syndrome of additional obscure retrogradely conducting ventricular-atrial connection, a gap is filled with significant diagnostic value, that has given numerous confusions in emergency and applied cardiology. The enrichment of ventricular pre-excitation with a new syndrome makes possible a more precise and correct diagnosis, hence restricting the possibilities of diagnosing of non-existing myocardial disease. Furthermore, the syndrome is of principle importance for the therapeutic behaviour of the disease.
