Abstract :
Accessory pathways (AP) are abnormal myocardial connections between atria and ventricles with
electrical conductive properties. We performed
radiofrequency (RF) catheter ablation in 66 patients with
manifest AP at Dr. Shariati Hospital during 5 years.
Bipolar mapping was used in 48 patients and unipalar
mapping in 18 patients to find the best site for RF energy
delivery. We calculated total duration of the procedures,
mean of RF energy dosage and delivery time, number of
the lesions, and the success rate in each mode. We found
that unipolar mode was preferred one for RF catheter
ablation of the free wall accessory pathways.
