The relative refractoryperiod, functional refractoryperiod and effective refractoryperiod (ERP) of right atrial, atrioventricular node and right ventricle were increased.
心房、房室结及心室相对不应期、功能不应期及有效不应期(erp)延长。
2
Objective to analyze the relation between the changes of fast pathway antegrade effective refractoryperiod after slow pathway ablation and the conductive features of atrioventricular node.
