How to Predict and Avoid Complete AV Block Complicating Radiofrequency Ablation of AV Nodal Slow Pathway
Slow pathway ablation is currently used to cure common and uncommon A-V node reentrant tachycardia (AVN RT). The technique has a success rate of about 100% and a 0.5%–2% risk of inadvertent complete AV block [1–4]. Although the risk of block is low, it is difficult to tolerate in patients with a benign arrhythmia, especially when they are young.
