The purpose of this study was to evaluate the influence of age on the mechanism of @entity4710 ( @entity4710 ). Previous studies have shown age and sex differences between certain @entity943 and especially changes in electrophysiological characteristics of @entity3153 . Four hundred and eighty five @entity1 aged 9-86 years, with @entity4710 and without @entity3153 in sinus rhythm, were studied. The esophageal or intracardiac electrophysiological study used a standardized atrial pacing protocol. Paroxysmal junctional @entity591 was induced in 475 @entity1 . The mechanism of @entity591 was not influenced by age and @entity2917 ( @entity2917 ) was found as the main cause of @entity4710 in all ranges of age. @entity2917 ( @entity2917 ) using a concealed accessory pathway (AP) had a similar incidence from youth to elderly. The ratio male/female (M/F) and the inducibility of other @entity943 ( @entity955 ) (AF/ @entity14387 ) were also found to be similar in all ranges of age. The age of the @entity1 did not influence the mechanism of the @entity591 . Most of PVST were related to a @entity2917 reentrant @entity591 . Concealed accessory pathway was identified with a similar incidence in young and old @entity1 .
