General term: Catheter ablation is a general term referring to elimination of electrical conduction in very specific areas of the heart. Two primary technologies are used to perform catheter ablation. Radiofrequency energy is a rapidly alternating electrical current that generates heat at the point of catheter contact. Cryo ablation uses super cooled nitrogen to freeze at the point of of catheter contact.
