[Radiofrequency fulguration in patients with reciprocating tachycardias].
The use of radiofrequency for catheter ablation of accessory pathways and dual AV nodal pathways has been recently introduced. In this paper the results obtained in 5 patients are reported. Three patients had accessory pathways and 2 a dual AV nodal pathway. After a complete electrophysiologic study, a 7F Door Knob catheter coupled to a Radionics radiofrequency generator delivering a maximum of 16 watt at 480 KH was used to ablate the abnormal pathway. Success was obtained in every patient at times varying from 30 sec to 3 min, using 3 to 17 energy deliveries. These results include the first successful ablation of a left lateral bundle with radiofrequency using an energy of only 16 Watt.
