Comparison of changes which was made by amiodarone in refractory periods

Variable	Mean	P
Δ AERP-AVN	41.95±26.36	<0.001
Δ AERP-AP	22.30±30.90
Δ RERP-AVN	37.32±38.68	<0.001
Δ RERP-AP	20.86±26.36

Data are presented as mean±SD. Δ=The difference between parameters before and after amiodarone infusion; AERP-AVN=Antegrade effective refractory period of the atrioventricular node; RERP-AVN=Retrograde effective refractory period of the atrioventricular node; AERP-AP=Antegrade effective refractory period of the accessory pathway; RERP-AP=Retrograde effective refractory period of the accessory pathway; SD=Standard deviation
