Abstract
A method, including receiving from mapping electrodes positioned at locations within a heart, signals indicating electrical activity in tissue contacting the electrodes, and processing the signals to identify, for each location, at least one corresponding LAT in a cycle of a heart. For each location, an earliest LAT in the cycle is identified, and an electroanatomical map including mapping points having respective locations and showing the earliest LAT at each location is generated and rendered. An input selecting a subset of the points is received, and a time range containing the earliest LAT of a majority of the points in the subset is identified. One or more outlying points in the subset are identified, and a second LAT, later than the earliest LAT in the cycle is found among the at least one identified LAT identified at the outlying points. The map is updated to display the found second LAT.
