Medicines such as beta-blockers (eg. metoprolol, atenolol, propranolol), calcium channel blockers (diltiazem or verapamil) or digoxin slow down the time it takes for the electrical impulses to travel through the heart (slowing down the AV node). This makes the heart rate stay at a slower rate. The choice of medication may be affected by your other medical conditions.

When your heart rate cannot be controlled with medications the doctor may recommend that you have an AVJ ablation/device implantation. In this procedure, a catheter is placed over the AV node (the electrical connection between the top and bottom chambers of the heart) and the tissue is ablated or burned (ablation). This will prevent the irregular impulses from traveling down to the ventricles. However, you will need a pacemaker so that your heart rate can be maintained at a normal rate (AVJ ablation / Pacemaker).
