Electrophysiology studies AV node ablation

• This procedure involves the use of 3 catheters to correct arrhythmias in the heart that cannot be treated with medicine.
• An electrode catheter is inserted into the right atrium along the wall.
• A mapping catheter is also inserted into the same chamber.
• An arrhythmia is induced by the electrode catheter.
• The mapping catheter maps the electrical pathway created by the arrhythmia.
• An ablation catheter is inserted into the right atrium and ablates the mapped regions.
