[Pathogenesis of various types of tachycardia in childhood].
As many as 33 children with different patterns of tachyarrhythmia were subjected to transesophageal pacing of the left atrium. Thi incidence of the orthodromal pattern of reciprocal AV-tachycardia was the highest (10 patients); antidromal reciprocal AV-tachycardia was only noted in 1 patient. Four patients turned out to have latent Kent's bundle which provoked the development of tachycardia attacks. The slow-fast pattern was revealed in both cases of nodal tachycardia. Among atrial tachycardias, monofocal automatic one was encountered most frequently (9 patients) and only one patient was diagnosed to suffer from reciprocal atrial tachycardia. The determination of the pathogenesis of tachycardia in children with the WPW syndrome is of importance for solving the problem of the successive medicamentous and non-pharmacological treatment character.
