Glossary of Terms

Catheter Ablation
Catheter ablation is a curative procedure that involves the application of energy through a catheter tip to cauterize electrical tissue causing the arrhythmias. This is usually performed as a part of an electrophysiology study demonstrating an abnormality amenable to ablation. Radiofrequency catheters are positioned close to the abnormal electrical tissue and heat energy is passed through the tissue. The goal is to cauterize the abnormal electrical site to cure the arrhythmia.
