In 3 cases of Wolff-Parkinson-White syndrome the QRS complexes were found to be formed by fusion between the normal and premature activation processes. In one of these cases a re-entry tachycardia was shown, with antegrade conduction occurring through the His bundle and retrograde conduction bypassing it. These observations are consistent with the hypothesis that an anatomical bypass of the normal atrioventricular conduction system is responsible for Wolff-Parkinson-White syndrome. One case of Lown-Ganong-Levine syndrome with recurrent atrial flutter was found to have a reduced A-His interval representing the time from low right atrial to His bundle.
