An atrial pacing-induced reverse conduction pattern of the alternating Wenckebach periodicity was observed in 5 of 42 children (12%) during electrophysiologic study. This conduction pattern is a reverse of the usual alternating Wenckebach periodicity: During an underlying 2:1 atrioventricular conduction block there is progressive shortening of the conduction time of the conducted impulses with termination in a lower degree of block. This reverse alternating Wenckebach periodicity may be caused by a mechanism similar to that in other Wenckebach phenomena.
