Radionuclide phase analysis(RPA) was carried out in 15 normals and 17 Wolff-Parkinson-White(W-P-W)syndrome before and after RFCA(radiofrequency ablation).VW(ventricular phase angle width) for the patients before RFCA were significantly wider than that for the normal group and the patients after RFCA(P<0.01)
but there was no significant difference between normal group and the patients after RFCA(P>0.05). Also
no significant difference in the left ventricular cardiac function was observed among the normal subjects
before and after RFCA(P>0.05).The localization of bytract was correlated well with the electrophysiological study.Usually the pre--excite sites still existed within one week after RFCA
but disappeared after one week.In conclusion
RPA is a noninvasive
effective method for diagnosing W-P-W syndrome
estimating the effect of RFCA and detecting cardicac function.
