Abstract
Background- Noninvasive methods for identification of accessory pathway(s) (AP) location in pre-excitation syndrome have always been desirable. Given the non-invasiveness and other advantages of radionuclide ventriculography (RVG), this study was performed to verify the efficacy of RVG in determining the location of accessory pathway(s) in patients with Wolff-Parkinson –White (WPW) syndrome.
Methods- Fourteen patients with WPW syndrome were enrolled in this study and they underwent RVG scanning followed by electrophysiologic study (EPS) within a couple of days.

Results- After we compared the scintigraphic and electrophysiologic results, RVG showed that 11 patients had one AP and 3 patients had dual APs. The existence of dual pathways were confirmed by EPS only in two patients .RVG did not identify dual pathways in one patient. Conclusion- We concluded that RVG scanning could be considered as a noninvasive procedure before EPS. Considering the location of APs, RVG identified their location (in comparison with EPS) in 78.8% of the patients
