Radiofrequency
ablation is performed to correct an abnormal heart rhythm (arrhythmia).
It is usually done as part of an electrophysiology
(EP) study. An ablation is performed in an electrophysiology
lab by an electrophysiologist
(a cardiologist who specializes in these procedures) with assistance
from a specially trained team of technologists
and nurses.
Your abnormal heart rhythm may be caused by an abnormal electrical pathway that you had at birth, or it may be caused
by a section of the heart that has been injured by heart attack, surgery or even an infection. If your cardiologist has determined that your arrhythmia may
have such a specific cause, he or she may recommend radiofrequency ablation.
During your EP study, the exact area that is causing the arrhythmia is located, and then a special catheter called an ablating electrode catheter
is positioned at the site of the abnormal electrical activity. Radiofrequency energy passes through the catheter, heating the tip and intentionally damaging the
small area of heart tissue that is causing the problem. The scar tissue that is created as the heart tissue heals is no longer able to carry electrical impulses.
Because of this, the abnormal rhythm is eliminated. Ablation is a safe and highly effective procedure that only treats the very small area of your heart muscle
causing the irregular heartbeat. To help you relax and stay comfortable during the procedure, you will receive medication.
An ablation can take one and one half to three hours to complete. You will then be asked to lay flat for at least three hours after the procedure. If your doctor
orders a radiofrequency ablation for you, you will receive more detailed information and instructions when the procedure is scheduled.
