title: Reciprocating tachycardia with only odd-numbered beats in the Wolff-Parkinson-White syndrome.
abstract: A case of Wolff-Parkinson-White syndrome with reciprocating tachycardia from retrograde Kent's bundle conduction is described. The paroxysms of reciprocating tachycardia manifested with the unusual, and hitherto unreported, feature of only odd-numbered beats. The phenomenon is explained on the basis of alternate anterograde conduction through two A-V nodal pathways.
