AV nodal ablation

An AV nodal ablation procedure is an invasive medical procedure that uses heat energy to create a small scar in the heart and block electrical signals travelling from the top to the bottom chambers of the heart. The procedure is only recommended for patients who already have a pacemaker, when other treatment options have failed to control their abnormally fast heart rates. AV nodal ablations are performed in hospital via the groin under local anaesthetic and sedation.
