摘要：
A system and method for improving ablation procedures is presented. The method may comprise measuring EGM signals performing three dimensional mapping of the EGM signals and detecting a location for ablation based on the mapping. The method may further comprise creating a potential duration map, a local activation time map, and a bipolar voltage map. The method may further comprise creating a PDM by defining a window of interest (WOI) comprising at least a cycle length calculating previous heart beats based on the cycle length and reference annotation and assigning the heart beats within the cycle length of the WOI to the WOI. The method may further comprise detecting a location for ablation by finding start and end potential durations for the WOI calculating a potential duration value using the start and end potential durations selecting an ablation point and using the selected ablation point as the detected location
