Safety analysis of intravenous amiodarone in wolff parkinson white syndrome with atrial fibrillation / 解放军医学杂志

Objectives To evaluate the safety of intravenous amiodarone in patients with atrial fibrillation and rapid ventricular response via an accessory pathway. Methods Sixteen patients with Wolff Parkinson White syndrome (W P W group) and 16 patients with concealed accessory pathway (control group) were included. The anterograde effective refractory period of accessory pathway (ERP AP ) in W P W group and the effective refractory period of atrioventricular node (ERP AVN ) in control group were measured. Then 150mg of amiodarone was injected intravenously in 10min, the ERP AP and ERP AVN were remeasured 10min later. Results After amiodarone injection, ERP AP was increased slightly ( P
