Abstract
One embodiment includes a cardiac ablation system, including an ablation probe including at least one ablation application element to ablate tissue in a chamber of a heart of a living subject, a tracking module to track a position of the at least one ablation application element within the heart, a memory to store a map of the chamber of the heart and store a different, respective default ablation-parameter set for each different region of the chamber, and processing circuitry to segment the map of the chamber into the different regions, receive a user input indicative of commencement of an ablation procedure, identify, responsively to the tracked position, a region of the chamber with which the at least one ablation application element is in contact, retrieve the respective default ablation-parameter set assigned to the identified region, and apply the retrieved default ablation-parameter set in controlling the ablation procedure.
