One or more characteristics of a patient's heart, such as atrioventricular (AV) interval, PR interval and/or heart rate are monitored during an ablation procedure. A change in the heart characteristic detected during the ablation may indicate successful denervation. Accordingly, successive new locations may be targeted for ablation until a change is detected.3/5 r44 Lr, Lo) 4 00 (n C) Lo LL1
