Hello, I'm an expert in cardiology with extensive experience in catheter ablation procedures. Catheter ablation is a procedure used to treat certain types of abnormal heart rhythms, known as arrhythmias. During the procedure, a long, flexible tube called a catheter is inserted into a vein in the groin or neck and guided to the heart. Once in place, the catheter delivers radiofrequency energy or cryoenergy to the heart tissue causing the arrhythmia, effectively "abilitating" or scaring the tissue so it can no longer send the abnormal electrical signals. Patients are usually awake during the procedure, but you may receive medication to help you relax. Local anesthesia is applied to the area where the catheter is inserted to minimize discomfort. The procedure is generally well-tolerated, and patients often describe the sensation as a warm or cool feeling, depending on the type of energy used. It's important to note that while patients are awake, they are closely monitored for any signs of discomfort or complications. The decision to keep a patient awake or to use general anesthesia depends on various factors, including the patient's preference, the complexity of the procedure, and the physician's judgment. read more >>

This is so the doctors and nurses can give you medications and fluids through your vein during the procedure. You will be given a medication through your IV to help you relax. Depending on the type of ablation you have, you may or may not be awake during your procedure.read more >>
