Abstract
Selective ablation of slow pathway by radiofrequency (RF) current in 3 4 patients with atrioventricular (AV) node pathways and tachycardia wa s performed with two methods in our section; posterior approach was us ed in the first 12 patients, the slow pathways were ablated successful ly. Inferior approach was performed in the other 22 patients. Slow pat hways were interrupted in 14 patients. Retrograde fast pathways and/or slow pathways were ablated in 6 patients. Retrograde fast pathways an d slow pathways were abolished and antegrade fast pathways were injure d transitorily in 2 cases. The total procedure time was shorter, RF ap plications were fewer by inferior approach than by posterior approach (P < 0.05). Both antegrade and retrograde conduction of fast pathways had not been affected after slow pathways were ablated (P > 0.05). Aft er a mean of 8 months follow-up, two patients recurred and were ablate d successfully again. We come to the conclusion that inferior approach might be a preferable method compared with posterior approach; the sl ow pathways is the compact node and its posterior input of transitiona l cells; the retrograde fast pathway may be the anterior superficial g roup of transitional cells and is not always in the same location of a ntegrade fast pathway.
