Department of Cardiology, Xian gaox in hospital, X ian 710075, Shanx,i China [ Abstract] O b ective To analyze the correlation bewt een atrioventricular block (AVB) and continuousAV non 11 proportion during the radiofrequency catheter ablation (RFCA ) procedures in patientswith atrioventricular nodal reentrant tachycardia ( AV RT) and the characteristicsofAVB in order to provide amethod to preventAVB from theRFCA ofAV - RT. M e thod Cardiac electrophysiology data of 113 consecutive patientswere analyzed retrospectively. The relationship betweenAVB and clinicaldata, proportion ofAV numbers and proportion ofAV amplitude during the radiofrequency abla- tionwas analyzed. R esults The transientAVB occurred in 21 patients ( 36. 84% ) when the continuous AV non 11 proportion appeared, and the incidence ofAVBwas0. 52% when therewas no continuousAV non 11proportion during the radiofrequency currentdelivering, as for as the incidence ofAVB, therewas a significant differencesbetween the wt o groups w ith or without continuousAV non 11 proportion(P 0. 05). And therewas not significant difficences in the relationship bet
