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.

The same.: "catheter ablation" and "radiofrequency ablation" are really terms for the same procedure. Some ablations use other energy sources (like freezing) to perform ablation, but rf is the most common.

Ablation : Catheter ablation is a more general term, there is also cryo ablation besides RF ablation
