Cardiac Ablation


A cardiac ablation is a procedure to treat an arrhythmia, or abnormal heart rhythm. Your heart rhythm is controlled by electrical pathways in your heart. During cardiac ablation, energy is sent to the area of your heart that has an electrical problem. The energy causes a tiny area of the heart muscle to scar. This stops the electrical problem and allows your heart to beat regularly.



You may need any of the following:

  • Pain medicine takes away or decreases pain. Do not wait until the pain is severe before you take your medicine.
  • Blood thinners help prevent blood clots. A clot can cause a life-threatening problem, such as a stroke or heart attack. You will need both injections and pills. Once your blood tests show that the pills are working, you may be able to stop the injections.
  • Antiarrhythmics help slow your heartbeat and make it more normal.
  • Steroids decrease inflammation.
  • Antiulcer medicine helps decrease the amount of acid that is normally made by the stomach. You may need to take this medicine to help the lining of your stomach heal or prevent an ulcer.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider or cardiologist in 7 to 10 days or as directed:

You will need regular blood clotting tests to monitor your blood thinner medications. You will also need EKGs to check your heart rate and rhythm. Write down your questions so you remember to ask them during your visits.

Wound care:

Carefully wash your catheter insertion site as directed. Dry the area and put on new, clean bandages. Change your bandages when they get wet or dirty. You may bathe 24 hours after your procedure, or as directed.

Holter monitor:

You may need to use a Holter monitor to check your heart rate and rhythm at home. Ask how and when to use it. If you have questions, ask your healthcare provider for more information about Holter monitors.
