Programmed transesophageal electrical stimulation was used to examine 733 rural inhabitants aged 16 to 70 years. Conduction dissociation along the atrioventricular node was revealed in 65 (8.8%) of the examinees, out of them 12 had induced paroxysms of atrioventricular nodal tachycardia. Atrioventricular tachycardia involving the accessory anomalous pathways was provoked in 10 subjects. Among them 2 had apparent, 1, latent, and 7, obscure forms of the Wolff-Parkinson-White syndrome. The induced paroxysms of atrioventricular tachycardias were sustained in 45.5% of the cases. Only 50% of the subjects had clinical signs of tachycardia in their medical histories.
