One approach to this problem has been the use of radiofrequency ablation of the AV node to create complete heart block, followed by implantation of a pacemaker. Symptom relief is good, with attendant ...

Atrioventricular (AV) nodal ablation with pacing is an alternative therapeutic option in patients with atrial fibrillation (AF) and difficult-to-control ventricular rates that are unresponsive to ...

Explaination: Once again the AV nodal blocking medications should not be used since blocking the AV node allows more impulses to travel through the accessory pathway thus making the ventricular rate ...
