Use of adenosine-sensitive nondecremental accessory pathways in assessing the results of radiofrequency catheter ablation.
Adenosine can cause conduction block in about 20% of nondecremental accessory pathways. Along with atrial activation mapping, adenosine may help differentiate retrograde AV node conduction versus residual accessory pathway conduction after radiofrequency catheter ablation; however, it is important to test the accessory pathway response to adenosine before ablation, particularly with a concealed accessory pathway.
