Abstract
The Wolff-Parkinson-White Syndrom signifies an extreme example of a much more frequent electrocardiographic change, which is characterized by a slow variation of the PQ-interval and which is represented by Δ. From this standpoint there is in the curves mentioned neither shortening of PQ nor lengthening of QHS. Δ represents always the same electrocardiographic change, regardless of its form or shape, for Hits wave shows all transitions from one form to another in one and the same individual, especially following injections of acetylcholine. A distinct cardiac hyperexcltability seems to be the requirement for Ihe formation of wave Δ. Attacks of paroxysmal tachycardia are to be considered as the outstanding sign. Through intravenous injection of chinidine and potassion chloride Δ can he made to disappear, and in healthy persons it can he made to appear through injections of adrenaline. Δ shows the existence of premature ventricular excitation. This is supposed to follow upon direct auriculo-ventricularr conduction to the bundle of IHs. Δ can he present in nodal rhythm without a visible T-wave. The confine lion cannot be attributed to a bundle of Kent. It is' effected through a direct connection between the noded Tawara and the ventricle, analogous somewhat lo the collateral of Mahalm. The connections are supposed a Δ-wave. This path is supposed to he taken only during a stale of increased excitability. Thus the constantly observed finding of these electrocardiographic changes with functional disturbances becomes understandable. © 1944 S. Karger AG, Basel.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
