What you can expect

Atrial flutter ablation is done in the hospital. You'll receive a medication called a sedative that helps you relax.

Once the sedative takes effect, a small area near a vein, usually in your groin, is numbed.

The doctor inserts a long flexible tube (catheter) into the vein. He or she carefully guides the catheter into your heart.

Sensors on the tip of the catheter send electrical impulses and record your heart's electricity. Your doctor uses this information to determine the best place to apply the ablation treatment.

Heat (radiofrequency energy) is applied to the target area, damaging the tissue and causing scarring. The scarring helps block the electrical signals that are causing your atrial flutter.

Atrial flutter ablation typically takes two to three hours. Afterward, you'll be taken to a recovery area where doctors and nurses will closely monitor your condition.

Depending on your condition, you may be allowed to go home the same day or you may spend a night in the hospital.
