Abstract: A case of intermittent Wolff-Parkinson-White syndrome is reported, which is the first report of an apparent bradycardia-dependent block in the accessory pathway. When the P-P interval gradually lengthened to a critical value of 0.89 second or more, preexcitation failed to occur, but thereafter, when the P-P interval gradually shortened to 0.89 second or less, preexcitation again occurred. These findings seem to suggest that bradycardia-dependent block occurred in the accessory pathway. In the electrocardiogram taken on another day, ...
