Electrophysiologic Testing and Radiofrequency Ablation
After being diagnosed with AVNRT, patients can also undergo an electrophysiology (EP) study to confirm the diagnosis. Catheter ablation of the slow pathway, if successfully carried out, and cures 95% of patients with AVNRT. The risk of complications is quite low.
Prevention
Triggers such as alcohol and caffeine should be avoided.
